| 9. | This paper investigates the types of acrylic modified solvent ( methyl and dimethyl benzene ) , the usage of acrylic acid , the usage of initiator , esterification time , and preliminarily tests the dehydration rate of modified demulsifier 摘要对丙烯酸改性溶剂的种类(甲苯和二甲苯) 、丙烯酸的用量、引发剂的用量以及酯化时间进行考察,并针对改性后的破乳剂的脱水速度和脱水率进行了初步的检测。 |
| 10. | When the reaction time was soomin , the acid number of esterify production was least . it shows that hydroxy peak of pea4 would be least at 300min , the hydroxy peak of pea23 was almost disappeared at 120min . in macroscopical side , the acid number can only indicate that superflous aa was reduced along with esterify reaction and pumping water 因此,宏观手段和微结构表征表现的酯化反应趋势是一致的,而宏观上的酸值只能反应过量丙烯酸的随着酯化反应和除水作用而减少,并不能完全真实反映酯化进程,而微观上进一步证实了不同分子量的聚乙二醇的酯化所需的酯化时间随着分子量的增大而减少。 |
