| Applications | Uses: Used in plastisols and coating pastes, as a low-volatility plasticizer for vinyl resins, as a stationary liquid phase in chromatography, and to make vinyl mixes resistant to heat and detergents, [HSDB], Plastic Composites Manufacturing [Category: Industry], It is used for making vinyl mixes which have to withstand heat and resist migration and extraction by detergents, also useful in the technology of plastisols and coating pastes, General-purpose, low-volatility plasticizer for vinyl resins, pure grade as stationary liquid phase in chromatography., Methods of Manufacturing: The first step, alcoholysis of phthalic anhydride (PA) to give the monoester, is rapid and goes to completion. The reaction generally starts at elevated temperatures and proceeds exothermically. The second step is the conversion of the monoester to a diester with the formation of water. This is a reversible reaction and proceeds more slowly than the first, thus determining the overall rate of reaction. To shift the equilibrium towards the diester, the water of reaction is removed by distillation. The rate of reaction can be influenced by the choice of catalyst and the reaction temperature. For fast conversion rates, high reaction temperatures are generally used. However, these are influenced by the boiling point of the alcohol and, or the type of catalyst. ... Currently, nearly all major phthalate producers use amphoteric catalysts for the esterification of high boiling alcohols. ... The reaction temperatures for the amphoteric catalysts are about 200 °C. At this temperature side reactions are minimized, and the alcohol can be recycled without purification. By using this type of catalyst, over 99.5 % conversion to diester can be achieved., Phthalates, U.S. Production: (1972) PROBABLY GREATER THAN 4.54X10+5 G, (1975) PROBABLY GREATER THAN 4.54X10+5 G, Production volumes for non-confidential chemicals reported under the Inventory Update Rule.
