METHOD OF MAKING PLASTICIZERS |
摘要 |
A process for the titanate catalyzed preparation of plasticizers from polycarboxylic acids and alcohols which minimizes waste water and is energy efficient. The reaction product is treated with aqueous caustic and is then filtered using an absorbent medium which removes titanium, caustic, acid salts and water. The need for water washing is obviated, and the final plasticizer product has excellent properties.
