Taw qhia
Amyl butyrate, tseem hu ua amyl butyrate lossis 2-amyl butyrate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm amyl butyrate:
Cov Khoom: Amyl butyrate yog cov kua tsis muaj xim uas muaj cov ntxhiab tsw tsw ntxhiab ntawm cov dej ntws los yog cov kav dej ntev. Nws muaj ntsim, fruity aroma thiab soluble nyob rau hauv ethanol, ether thiab acetone.
Kev Siv: Amyl butyrate yog siv dav hauv kev lag luam tsw thiab tsw qab, thiab yog siv dav hauv cov txiv hmab txiv ntoo, peppermint thiab lwm yam khoom qab zib thiab fragrances. Nws kuj tseem siv tau rau kev siv hauv kev lag luam xws li kev npaj cov txheej, yas, thiab cov kuab tshuaj.
Txoj kev npaj: Kev npaj ntawm amyl butyrate tuaj yeem hloov pauv. Ib txoj kev npaj ntau yog los hloov cov butyric acid nrog pentanol nyob rau hauv lub xub ntiag ntawm ib tug acidic catalyst xws li sulfuric acid los yog formic acid los tsim amyl butyrate thiab dej.
Cov ntaub ntawv kev nyab xeeb: Amyl butyrate feem ntau muaj kev nyab xeeb raws li kev siv ib txwm siv, tab sis cov hauv qab no tseem yuav tsum tau sau tseg:
1. Amyl butyrate yog flammable thiab yuav tsum tau zam thaum lub sij hawm cia thiab siv los ntawm tsis txhob sib cuag nrog qhib nplaim taws los yog kub kub.
2. Ntev mus ntev ntawm cov vapor los yog kua nrog amyl butyrate tuaj yeem ua rau khaus ntawm daim tawv nqaij, qhov muag thiab ua pa. Yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha thiab siv cov hnab looj tes tiv thaiv, tsom iav, thiab kev tiv thaiv tsim nyog thaum siv.
3. Yog tias koj noj lossis nqus tau amyl butyrate, koj yuav tsum mus ntsib kws kho mob tam sim ntawd thiab muab kev pab kho mob.
