缩合产物
缩合物
Examples
- The polysaccharides are all condensation products of hexoses or other monosaccharides .
多糖全部是己糖或其它单糖的浓缩产物。 - Polyester resins are the condensation products of polybasic acids and polyols
聚酯树脂是多元酸和多元羟基化合缩聚而成。 - Cp condensation product
冷凝物,浓缩物 - The traditional catalyst used in acetal ( ketal ) synthetic reaction is strong inorganic acid . but there is some limits to its use because of its side reaction , strong erosion and liability to pollute the environment . molybdophosphoric acid is used as catalyst and three condensation products are prepared through the direct reaction of aldehydes ( ketones ) and ethylene . in addition , several elements of affecting the reaction is researched . it is proved that molybdophosphoric acid is very active as catalyst in less addition , the product yield is quite high and the quality of reuse is quite good
缩醛(酮)合成反应的传统催化剂为无机强酸，但由于副反应多、腐蚀性强和易污染环境等缺点，其使用受到限制.用磷钼酸为催化剂，通过醛(酮)与乙二醇直接反应得到了三种缩合产物.对影响反应的诸因素进行研究,结果表明，用磷钼酸作催化剂，用量小，活性高，产品收率较高，且重复使用性能较好 - Abstract : the traditional catalyst used in acetal ( ketal ) synthetic reaction is strong inorganic acid . but there is some limits to its use because of its side reaction , strong erosion and liability to pollute the environment . molybdophosphoric acid is used as catalyst and three condensation products are prepared through the direct reaction of aldehydes ( ketones ) and ethylene . in addition , several elements of affecting the reaction is researched . it is proved that molybdophosphoric acid is very active as catalyst in less addition , the product yield is quite high and the quality of reuse is quite good
