Hendecanoic acid (CAS # 112-37-8)
Daim ntawv thov:
1.Undecanoic acid yog ib hom roj chromatography nrog cov qauv sib xyaw, cov roj capillary chromatography sab hauv txheej txheem tau siv los txiav txim siab cov tshuaj tiv thaiv dehydroacetic acid, benzoic acid thiab sorbic acid hauv cov zaub mov, cov qauv rov qab yog nyob nruab nrab ntawm 96% thiab 104%, tus qauv linear kev sib raug zoo yog qhov zoo, cov coefficient ntawm kev hloov pauv ntawm cov qauv kev txiav txim me me, dehydroacetic acid yog 0.71%, benzoic acid yog 0.82% thiab sorbic acid yog 0.62%. Nws yog qhov yooj yim, ceev thiab raug. Ntxiv rau qhov no, nws tseem tuaj yeem siv los txiav txim siab cov ntsiab lus ntawm ntau yam khoom noj hauv cov zaub mov [5-7].
2.Nws yog siv nyob rau hauv zus tau tej cov additives uas muaj cov organic acids thiab nruab nrab-chain fatty acids, uas yog siv los tshuaj ntsuam tawm medium-chain fatty acids (caprylic acid los yog nonanoic acid) thiab organic acids (citric acid) nrog ntau cov tshuaj tua kab mob. los ntawm kev kho cov kab mob sib txawv nrog cov MCFAs thiab OAs sib txawv, thiab tom qab ntawd muab ob qho tib si hauv qhov sib piv tsim nyog los ua kom lawv ua kom muaj zog sib koom ua ke, txhawm rau xyuas kom meej tias cov Cov nyhuv tshuaj tua kab mob tuaj yeem muaj zog dua los ntawm kev txo cov koob tshuaj nruab nrab-chain fatty acids thiab organic acids [8].
3.Undecanoic acid yog siv nyob rau hauv cov organic synthesis thiab raws li ib tug yas regulator.
