A process for producing a polyester polyol comprising reacting a recycle stream selected from recycled PET carpet, carpet fiber, containers, textiles, articles or mixtures thereof, with a glycol in a reactor, thereby forming a digested product stream comprising polyols, and an undigested stream; and then reacting the digested product stream with a hydrophobe selected from dimer fatty acids, trimer fatty acids, oleic acid, ricinoleic acid, tung oil, corn oil, canola oil, soybean oil, sunflower oil, bacterial oil, yeast oil, algae oil, castor oil, triglycerides or alkyl carboxylate esters having saturated or unsaturated C6-C36 fatty acid units, saturated or unsaturated C6-C36 fatty acids, alkoxylated castor oil, saturated or unsaturated C9-C18 dicarboxylic acids or diols, cardanol-based products, recycled cooking oil, branched or linear C6-C36 fatty alcohols, hydroxy-functional materials derived from epoxidized, ozonized, or hydroformylated fatty esters or acids, or mixtures thereof.
一种生产聚酯多元醇的工艺,包括在反应器中将选自回收 PET 地毯、地毯纤维、容器、纺织品、物品或其混合物的回收流与乙二醇反应,从而形成包含多元醇的消化产物流和未消化流;然后将消化产物流与亲水剂反应,亲水剂选自具有饱和或不饱和 C6-C36 脂肪酸单元的二聚脂肪酸、三聚脂肪酸、油酸、蓖麻油酸、桐油、玉米油、菜籽油、大豆油、葵花籽油、细菌油、酵母油、藻油、蓖麻油、甘油三酯或烷基羧酸酯、饱和或不饱和 C6-C36 脂肪酸,烷氧基化蓖麻油,饱和或不饱和 C9-C18 二羧酸或二元醇,以贲醇为基础的产品,回收食用油,支链或线性 C6-C36 脂肪醇,由环氧化、臭氧或氢甲酰化脂肪酯或酸衍生的羟基功能材料,或它们的混合物。
