1.
In the presence of alkaline soap as emulsifier and catalyst, hydrogenated rosin sucrose esters (HRSE) were synthesized by transesterification reaction of hydrogenated rosin ethyl ester and sucrose under the conditions of (125±1)℃,molar ratio of hydrogenated rosin ethyl ester to sucrose 1 ∶1, pressure 0.
090MPa及无溶剂的条件下,通过氢化松香乙酯与蔗糖的酯交换反应合成了氢化松香蔗糖酯(HRSE)。
2.
The hydrogenated rosin (HR) and hydroxyethyl methacrylate (HEMA) based ester was synthesized in one step method.
用一步法制备了氢化松香与甲基丙烯酸β-羟乙酯(HEMA)酯化物,结果表明,以对苯二酚为阻聚剂,氧化锌为催化剂,用量为氢化松香的1%,反应温度240℃,氢化松香与HEMA的摩尔比为1∶1。
3.
By analyzing a plenty of practical production data,suitable conditions for controlling the product color during the production of hydrogenated rosin are concluded to be super grade rosin as raw material,melting time 5h and melting temperature 130150,molten rosin flow rate 400L/h,reaction temperature 240250.
另外还应尽量减少反应系统中的CO、CO2、SO2、重金属离子的含量,避免有色油类和空气进入反应系统,最后对产品进行水蒸气蒸馏,能得到颜色较浅的氢化松香产品。
6) tetrahydroabietic acid
全氢松香
补充资料：四氢化松香酸
分子式：
CAS号：
性质：又称四氢化松香或全氢松香。松香酸中枞酸型树脂酸的共轭双键在更苛刻的反应条件下全部氢化的产物。软化点大于79℃。酸值158mgKOH/g。折射率1.536。枞酸含量降为零。用途与二氢化松香相同。主要用作工业的乳化剂与分散剂。亦可用作不溶性偶氮或色淀颜料合成中的分散剂。
