4-Morpholineethanesulfonic acid CAS 4432-31-9 tuaj yeem siv los ua cov ntaub ntawv raw rau lub ntsej muag ntxuav, tshuaj zawv plaub hau ua npuas dej, tshuaj ntxuav tais diav, tshuaj ntxuav tes, thiab lwm yam
Shandong Ntseeg
Cov khoom lag luam yog sodium stearate methyl ester sulfonate, sodium laurate methyl ester sulfonate, sodium crotonate methyl ester sulfonate, thiab sodium palmitate methyl ester sulfonate.
Txoj kev npaj ntawm sodium stearate methyl ester sulfonate yog qhia ua piv txwv.
Cov txheej txheem kev npaj ntawm cov khoom no suav nrog kev npaj ntawm methyl stearate, sulfonation thiab neutralization ntawm methyl stearate.
Muab lard rau hauv cov tshuaj tiv thaiv kettle thiab ntxiv methanol hauv molar piv ntawm 1: 2.
Tom qab cua sov thiab dissolving nyob rau hauv stirring, ntxiv 0.3% sulfuric acid raws li lub catalyst. Tom qab cua sov thiab refluxing rau 6-7h, cov tshuaj tiv thaiv transesterification tau ua tiav.
Hauv qab ntawm lub lauj kaub yog methyl stearate, thiab tom qab ntawd cov methyl stearate raug xa mus rau sulfonation kettle.
