application
1, 6-hexanediol diacrylate can be used as a raw material for organic synthesis and an intermediate for chemical production, and can be widely used in plastics, adhesives, textiles, rubber, modified copolymers, etc.
Preparation
1, 6-hexanediol diacrylate was synthesized by esterification with 1, 6-hexanediol and acrylic acid as raw materials, strong acidic cationic resin D072 as catalyst, cyclohexane as water-carrying agent and hydroquinone as polymerization inhibitor. The experimental results show that the optimal esterification reaction conditions are as follows: "(acrylic acid):"(1,6-hexanediol) -2.2, catalyst dosage (total mass ratio with raw materials) 2.5%, polymerization inhibitor dosage (mass ratio with acrylic acid) 0.6%, water carrying agent dosage (total mass ratio with raw materials) 70O.4, reaction time 4h, reaction temperature 80~110 ℃, 1, 6-Hexanediol diacrylate. The yield of the product reached 93.88%.
Uses are widely used in plastics, adhesives, textiles, rubber, modified copolymers, etc.
Uses are widely used in plastics, adhesives, textiles, rubber, modified copolymers, etc.
