Preparation Method of PGDA
The preparation of 1,2-Propyleneglycol diacetate (PGDA) typically involves an esterification process, where propylene glycol reacts with acetic acid. Here is a general outline of the method used for preparing PGDA:
Mixing: Propylene glycol and acetic acid are mixed in the reactor in a specific molar ratio, typically with an excess of acetic acid to drive the reaction towards ester formation.
Catalyst Addition: The catalyst such as sulfuric acid, p-toluenesulfonic acid, or an acidic ion exchange resin is introduced to the mixture to facilitate the esterification.
Heating and Reaction: The mixture is heated to a suitable temperature (usually around 120-150°C) to initiate and sustain the reaction. The propylene glycol reacts with acetic acid, forming PGDA and water as a by-product.
Monitoring: The reaction progress is typically monitored by measuring the water content or by other analytical methods.
Distillation: Excess acetic acid and water are removed from the crude product, often via a distillation process.
Purification: The PGDA may undergo further purification steps to achieve the desired purity level, which can include additional distillation, filtration, or other separation techniques.
Quality Control: The final product is tested to ensure it meets specific standards and specifications.
Storage and Packaging: The purified PGDA is then stored and packaged appropriately for distribution.

Characteristics of PGDA
1,2-Propylene diacetate( PGDA) is a relatively new chemical, and its emergence solves many problems compared to the previous production
The product is more environmentally friendly, the purity is better, and a product is available because it has its own unique characteristics.
- Strong solubility, it is a strong solvent of alkyd resin, acrylic resin, polyester resin, nitrocellulose resin, chlorinated resin, PU curing agent, etc. Water-based resin synthesis, water-based curing agent diluent (good hydrophobicity, poor reactivity with NCO) and TEXANOL ester 12 used in water-based coatings.
- Non-toxic and low taste contains a light mint smell, in terms of the use of prohibited substances and harmful substance limits in line with the European Union RoHS Directive 2002/95/EC redraft Directive 2011/65/EU Appendix II limits requirements. PGDA has been listed in the United States Pharmacopeia NF XVI. It can partially replace high boiling point and high taste solvents such as cyclohexanone, isophorone, CAC, PMA and ethylene glycol monobutyl ether.
