摘要
以田菁胶(SG)为原料,3-氯-2-羟丙基三甲基氯化铵(CHPAC)为醚化剂,氢氧化钠为催化剂,异丙醇水溶液为分散剂,合成阳离子田菁胶。讨论了影响阳离子田菁胶取代度的主要因素,得出较优的合成条件为:n(NaOH)/n(SG)=0.4,n(CHPAC)/n(SG)=0.5,碱化温度20℃,碱化时间50 min,醚化温度50℃,醚化时间4 h,制得阳离子田菁胶的取代度为0.45。将阳离子田菁胶添加到洗发水中进行梳理性测试,结果表明其具有较好的调理性能。
Cationic sesbania gum （CSG） was synthesized by sesbania gum （SG） and 3 -ehloro -2 - hydroxypropyhrimethylammonium chloride （CHPAC） as starting materials with sodium hydroxide as catalyst. The reaction was performed in isopropyl alcohol aqueous solution. Main factors that affect the substitution degree of CSG were investigated. The optimum reaction conditions are as follows ： n （ NaOH ）/n （ SG）, 0.4 ; n（CHPAC）/n （SG）, 0.5; alkalization temperature, 20℃; alkalization time, 50 min; etherification temperature,50 ℃ ;etherification time,4 h. Under these conditions the substitution degree of CSG achieves 0.45. CSG product was formulated into shampoo and the test results show excellent combing performance.
