摘要:

研究了一种不含磷、氮的可生物降解高分子洗涤助剂——聚环氧琥珀酸钠.通过钨酸钠的催化作用,将马来酸酐与过氧化氢发生环氧化反应得到环氧琥珀酸钠,接着在引发剂Ca(OH)2作用下,环氧琥珀酸钠发生水溶液聚合反应得到聚环氧琥珀酸钠PESA.分别采用红外光谱、核磁共振对目标产物的结构进行表征,考察了钙螯合力、钙分散力、碱缓冲力等助洗性能.优化的聚合反应工艺条件如下:反应温度为90℃,反应时间为6 h,引发剂Ca(OH)2用量为4%,所得PESA的螯合钙离子能力(以CaCO3表示)最高为367.5 mg/g,最高分散力(以CaCO3表示)为112.8 mg/g.

Abstract:

Poly (disodium cis-epoxysuccinate) PESA as a non-nitrogen and non-phosphors biodegradable polymer showing good chelating ability to calcium and magnesium ions and good buffer capacity can be used in detergent industry. PESA Polymers were synthesized by solution polymerization of disodium cis-epoxysuccinate in the presence of calcium hydroxide as initiator, while disodium cis-epoxysuccinate obtained by epoxidation of maleic anhydride using sodium tungstate as catalyst and hydrogen peroxide as oxidation. The molecule structures of both materials were characterized by IR and 1H NMR. The detergent properties of PESA polymers were investigated. The optimum synthetic conditions were found:reaction temperature=90℃, reaction time=6 h, mass content of Ca(OH)2=4%. And the calcium chelating and dispersing abilities (Expressed as CaCO3) were quantified as 367.5 mg CaCO3/g and 112.8 mg CaCO3/g, respectively.

Key words: disodium cis-epoxysuccinate, non-phosphorus detergent polymer, solution polymerization
