Siv:
Phenylethyl isovalerate; Phenethyl 3-methylbutylrate feem ntau yog siv los ua cov khoom xyaw hauv cov txuj lom thiab cov khoom qab zib uas muab cov khoom noj qab haus huv, xws li txiv hmab txiv ntoo qab zib, dej qab zib thiab dej khov. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom siv raw rau cov tshuaj ntxuav, cov kuab tshuaj thiab cov roj nplua nyeem.
Txoj Kev Npaj:
Phenylethyl isovalerate; Phenyl 3-methylbutanol feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm acetophenone thiab isopropanol nyob rau hauv lub xub ntiag ntawm ib tug catalyst. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
1. Sib tov acetophenone thiab isopropanol hauv molar ratio.
2. Ntxiv qhov tsim nyog cov kua qaub catalyst (xws li sulfuric acid).
3. Do cov tshuaj tiv thaiv ntawm qhov kub thiab txias (feem ntau yog 0-10 ° C). Hauv cov xwm txheej tsis tu ncua, lub sijhawm tshuaj tiv thaiv yog ob peb teev mus rau kaum teev.
4. Tom qab cov tshuaj tiv thaiv tiav lawm, cov khoom yog purified los ntawm cov kauj ruam ntawm condensation, sib cais, ntxuav thiab distillation.
Cov ntaub ntawv kev nyab xeeb:
Phenylethyl isovalerate; Phenethyl 3-methylbutylrate feem ntau suav hais tias muaj kev nyab xeeb raws li kev siv ib txwm siv. Txawm li cas los xij, nws yog cov kua ua kua, tsis txhob cuam tshuam ncaj qha rau cov nplaim taws qhib lossis kub kub. Yuav tsum tau muab cia rau hauv qhov chaw txias, zoo-ventilated. Thaum siv, hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav tiv thaiv. Yog tias koj kov koj cov tawv nqaij lossis qhov muag los ntawm kev sib tsoo, yaug tam sim nrog dej ntau. Yog tias nqus tau lossis nqus tau los ntawm qhov yuam kev, nrhiav kev kho mob tam sim ntawd.
