What is the chemical structure of Di-iso-nonyl Phthalate?

Di - iso - nonyl phthalate (DINP) is a phthalate ester. The chemical formula of DINP is C26H42O4.
The basic structure of DINP is centered around a phthalate core. Phthalate esters are derived from phthalic anhydride. Phthalic anhydride has a cyclic structure consisting of two benzene - like rings (a naphthalene - like fused - ring structure with one of the rings having a carbonyl - oxygen double - bond and an oxygen atom bridging the two rings). When phthalic anhydride reacts with an alcohol, in this case, iso - nonyl alcohol, phthalate esters are formed.

The "iso - nonyl" part of DINP indicates the alkyl group attached to the phthalate moiety. Iso - nonyl alcohol has a branched - chain structure. Nonyl refers to a nine - carbon alkyl chain, and the "iso" prefix implies a specific branching pattern. In the formation of DINP, two iso - nonyl groups are esterified to the two carboxyl groups of the phthalic acid (which is the product after the opening of phthalic anhydride).

The general structure of DINP can be thought of as follows: The central phthalate moiety has a planar, aromatic - based structure. At each of the two carboxyl - carbon positions of the phthalate, an iso - nonyl group is attached via an ester linkage. The ester linkage is formed through a condensation reaction between the carboxyl group of the phthalic acid and the hydroxyl group of the iso - nonyl alcohol, with the elimination of a water molecule.

The carbon atoms in the iso - nonyl chains are in a branched configuration. The branching can occur at different positions along the nine - carbon chain, which results in isomers of DINP. There are multiple isomers of DINP because there are different possible ways to arrange the branches in the iso - nonyl groups.

The overall structure of DINP gives it certain physical and chemical properties. The long - chain alkyl groups contribute to its non - polar character to a large extent. This non - polarity makes DINP relatively soluble in non - polar solvents and gives it good plasticizing properties. As a plasticizer, it is used to increase the flexibility, workability, and durability of polymers such as polyvinyl chloride (PVC).

The presence of the ester linkages in DINP means that under certain conditions, such as in the presence of strong acids or bases, hydrolysis can occur. Hydrolysis would break the ester bonds, reverting the DINP back to phthalic acid and the iso - nonyl alcohol.

In terms of its molecular geometry, the planar phthalate core and the relatively long and flexible iso - nonyl chains interact in a way that affects the packing of DINP molecules. In a polymer matrix, these interactions help to separate the polymer chains, reducing the intermolecular forces between the polymer chains and thus making the polymer more flexible.

The chemical structure of DINP also affects its environmental behavior. The non - polar nature makes it somewhat persistent in the environment as it is not easily degraded by simple aqueous - based processes. However, in the presence of appropriate microorganisms or under certain environmental conditions such as high - temperature and high - oxygen environments, biodegradation can occur. The degradation products can include phthalic acid and the breakdown products of the iso - nonyl chains.

In summary, the chemical structure of Di - iso - nonyl phthalate, with its phthalate core and two iso - nonyl ester - linked groups, is responsible for its wide range of uses as a plasticizer and its behavior in both industrial applications and the environment. The presence of isomers due to the branching in the iso - nonyl groups further adds to the complexity of its properties and behavior.

Gas chromatography and high – performance liquid chromatography are the most common.
Gas Chromatography (GC) is a highly effective method for determining the purity of DINP.Gas Chromatography is a highly efficient method for determining DINP purity. In GC, the sample is vaporized and carried by an inert gas (the mobile phase) through a column packed with a stationary phase.In GC, a sample is vaporized by an inert phase (the mobile phase), and then carried through a column containing a stationary phase. For DINP analysis, a capillary column with a suitable stationary phase, such as a non - polar or moderately polar phase, is often used.In DINP analysis, it is common to use a capillary with a suitable stationery phase, such a non-polar or moderately-polar phase. The different components in the DINP sample, including impurities, will interact differently with the stationary phase.The stationary phase will react differently with different components of the DINP sample. This includes impurities. Components with stronger interactions with the stationary phase will take longer to elute from the column, while those with weaker interactions will elute more quickly.Components that have stronger interactions with the stationary phases will take longer to elute, while those with weaker interaction will elute faster. As the components elute from the column, they are detected by a detector, typically a flame ionization detector (FID) for organic compounds like DINP.As the components elute, they are detected using a detector. For organic compounds such as DINP, this is usually a flame ionization detection (FID). The detector generates a signal proportional to the amount of each component.The detector produces a signal proportional with the amount of each compound. The chromatogram obtained from GC shows peaks corresponding to different components in the sample.The chromatogram from GC displays peaks that correspond to the different components of the sample. The area under each peak is proportional to the amount of the corresponding component.The area under each peak is proportional with the amount of a component. To determine the purity of DINP, the area of the DINP peak is compared to the total area of all peaks in the chromatogram.The area of the DINP peaks is compared with the total area of peaks in the chromatogram to determine the purity. The percentage purity of DINP is calculated as the ratio of the area of the DINP peak to the sum of the areas of all peaks (including DINP and impurities) multiplied by 100.The ratio of the area (including impurities and DINP) of the DINP peak divided by 100 is used to calculate the percentage purity of DINP. For example, if the area of the DINP peak is 950 and the total area of all peaks is 1000, the purity of DINP is (950 / 1000) * 100 = 95%.If, for example, the area of the DINP peaks is 950, and the total area is 1000, then the purity of DINP would be (950/1000) * 100 = 95%.

Similar to GC, the area under the peak corresponding to DINP is measured and compared to the total area of all peaks in the chromatogram to calculate the purity.In GC, the area below the peak corresponding DINP is measured. This area is compared to the total of all peaks on the chromatogram in order to calculate purity.

NMR can be used to identify and quantify the different chemical groups in the DINP molecule.NMR can be utilized to identify and quantify different chemical groups within the DINP molecule. By analyzing the NMR spectrum of a DINP sample, the presence of impurities can be detected based on the appearance of signals corresponding to chemical groups not characteristic of pure DINP.The presence of impurities in a DINP sample can be detected by analyzing the NMR spectra. This is done by looking for signals that are not characteristic of pure DINP. The relative intensities of the signals in the NMR spectrum can be used to estimate the amount of DINP and impurities.The relative intensities in the NMR spectrum are used to estimate the amounts of DINP and other impurities. For example, if a particular impurity has a characteristic NMR signal, and the intensity of this signal is compared to the intensity of the signals characteristic of DINP, an estimate of the impurity content can be made.If, for example, an impurity has its own characteristic NMR signal and the intensity is compared with the intensity of the DINP signals, it can be estimated how much impurity is present. However, NMR is often used in combination with other techniques like GC or HPLC, as it may not provide as accurate a determination of purity as these chromatographic methods for complex mixtures.NMR is used in conjunction with other techniques such as GC or HPLC because it may not be as accurate as these chromatographic methods when determining purity for complex mixtures.

By determining the elemental composition of the sample (carbon, hydrogen, oxygen in the case of DINP), any significant deviation from the theoretical elemental composition of pure DINP can indicate the presence of impurities.By determining the sample's elemental composition (carbon, hydrogen and oxygen in the case DINP), any significant departure from the theoretical elemental content of pure DINP may indicate the presence of contaminants. For example, if the measured carbon - to - hydrogen ratio is different from what is expected for pure DINP, it may suggest the presence of other organic compounds with different elemental ratios.If the carbon-to-hydrogen ratio is different than what is expected for pure DINP it could indicate the presence of organic compounds with other elemental ratios.
