部分变性植物油作苎麻油剂应用研究

将植物油磺化变性取代部分乳化剂,则解决自乳化油剂的成本问题.研究了植物油种类、硫酸变性工艺、辅助乳化剂等因素对油剂性能的影响,结果表明:渍(浓硫酸)为2%(对植物油体积),2%体积的浓硫酸以约0.5滴/秒的速度滴加到植物油中进行部分变性、再加入辅助复合乳化剂可得到自乳化油剂.该油剂克服了传统油剂所存在的问题,生产成本低,稳定性好,可在较低温度下实现给油,具有良好的推广应用前景.

Study on the use of modified vegetable oils as oiling agent for ramie

The sulfonated vegetable oils were used to replace partially the emulsifying agent for the resolution of the cost problem of the emulsifiers made in situ. The factors affecting the oiling agent performances were researched, such as oil kinds, process of modification with sulfuric acid, assistant emulsifiers, etc. Concd. sulfuric acid (2 vol % on the basis of the vegetable oils) was dropped into the oils at 0.5 drop/s, followed by the addition of assistant emulsifier compn. to give an emulsifier made in situ. This process overcame the existent problems for oiling agents, lowered the prodn. cost and bettered the stability. The oiling agent could be added at low temps. and had a good application future.
