Taw qhia
16-Hydroxyhexadecanoic acid (16-Hydroxyhexadecanoic acid) yog hydroxy fatty acid nrog cov tshuaj formula C16H32O3. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
16-Hydroxyhexadecanoic acid yog cov xim tsis muaj xim rau lub teeb daj nrog cov khoom siv tshwj xeeb hydroxyl. Nws yog ib tug fatty acid, muaj ib tug tej yam solubility, soluble nyob rau hauv non-polar solvents, xws li chloroform thiab dichloromethane, insoluble nyob rau hauv dej.
Siv:
16-Hydroxyhexadecanoic acid muaj ntau yam kev siv hauv tshuaj lom neeg. Nws yog ib qho tseem ceeb ua ib qho nruab nrab hauv cov organic synthesis, piv txwv li rau kev npaj cov tshuaj lom neeg lom neeg. Tsis tas li ntawd, nws tuaj yeem siv los ua cov khoom siv raw rau qee yam surfactants, hydroxyl-muaj polymers thiab lubricants.
Txoj Kev Npaj:
16-Hydroxyhexadecanoic acid feem ntau yog npaj los ntawm cov tshuaj synthesis. Ib txoj kev npaj ntau yog cov tshuaj tiv thaiv ntawm hexadecanoic acid nrog hydrogen peroxide, nyob rau hauv lub xub ntiag ntawm ib tug haum catalyst, nyob rau hauv tej yam kev mob tshwm sim kom tau lub hom phiaj cov khoom.
Cov ntaub ntawv kev nyab xeeb:
Raws li kev tuav tswj kom raug thiab khaws cia, 16-Hydroxyhexadecanoic acid feem ntau suav hais tias muaj kev nyab xeeb. Txawm li cas los xij, zoo li txhua yam tshuaj, nws yuav tsum tau siv raws li kev kuaj xyuas kev nyab xeeb. Yuav tsum zam kom raug ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab kev tiv thaiv tsim nyog (xws li hnab looj tes thiab tsom iav) yog qhov tsim nyog. Yog tias muaj kev sib cuag lossis nqus pa, ntxuav tam sim ntawd lossis nrhiav kev pab kho mob.
