| titleOfInvention | A kind of technique of epoxidized linseed oil and citric acid composite elasticizer |
| abstract | The invention discloses the techniques of a kind of epoxidized linseed oil and citric acid composite elasticizer, and citric acid, n-butanol, sulfuric acid are added in four mouthfuls of corkages, and 4 ~ 7h is stirred at 130 ~ 150 DEG C, tributyl citrate is obtained after dealcoholysis；Linseed oil, petroleum ether, formic acid are added in there-necked flask, is stirred at 60 ~ 70 DEG C by the speed of 300 ~ 500r/min, and instill the mixed solution of hydrogen peroxide and catalyst, after reacting 3 ~ 4 hours, stops stirring, adds in sodium hydroxide solution, acetic acid；The material mixing of gained; and 110 150 DEG C are heated under acidic catalyst, refuxing esterification reaction is carried out by water knockout drum, acetic anhydride is added in after cooling to 50 60 DEG C; acetylization reactions are carried out at 100 125 DEG C, 2 3h open vacuum after the reaction was complete and steam by-product acetic acid.Finally by neutralizing, washing, dry.The present invention has ehter bond, and more traditional citrate plasticizer compatibility is more preferable, is not easy to be precipitated, and epoxidized linseed oil is combined with citrate composite elasticizer, and performance is more excellent. |
