Cov khoom xyaw tsom xam - Cetearyl cawv

Cetearyl cawv yog sib xyaw ntawm cetyl cawv thiab stearyl cawv, thiab nws lub npe kuj yog ib qho kev sib xyaw ntawm ob lub npe. Vim hais tias cetyl cawv yog ib tug ncaj-chain saturated fatty cawv nrog 16 carbon atoms, stearyl cawv yog ib tug ncaj-chain saturated fatty cawv nrog 18 carbon atoms, yog li nws kuj hu ua cetostearyl cawv.

Lub hauv paus chiv keeb ntawm ceteryl cawv:
Lo lus "spermaceti" los ntawm whales. Ib lub sij hawm ntev dhau los, tib neeg tau rho tawm cov roj ciab los ntawm lub taub hau ntawm toothed whales xws li phev whales. Thaum txias rau 0 ° C, cov khoom tsim tawm yog spermaceti, uas tuaj yeem siv rau hauv kev tsim cov khoom tu tawv nqaij thiab cov cuab yeej precision. Thiab qib high-qib lubricants rau watches thiab moos. Cov khoom tseem ceeb yog cetyl glycol ester, thiab qee qhov yog cetyl glycol ester ntawm myristic acid thiab lauric acid. Lub saturated ncaj-chain qauv ntawm 16 carbons yog txuam nrog lo lus "spertiaceti".

Qhov chaw ntawm Cetearyl Alcohol:
Pom qhov no, koj puas txhawj xeeb tias lub hauv paus ntawm cetearyl cawv tsis zoo?

Tsis txhob txhawj, xav txog dab tsi 16-carbon saturated fatty acid hu ua? Yog, nws yog palmitic acid. Okay, kuv lees tias lawv muaj ntau lub npe. Raws li lub npe qhia, koj tuaj yeem kwv yees tias nws keeb kwm cuam tshuam nrog cov nroj tsuag.

Feem ntau ntawm cetearyl cawv siv niaj hnub no yog tsim los ntawm cov txiv maj phaub roj thiab xibtes roj.

Cov lus qhia txog kev paub txog raw khoom:

Qhov sib piv ntawm cetearyl cawv: stearyl cawv suav txog li 65 ~ 80%, cetyl cawv muaj txog li 10 ~ 35%, feem ntau suav tias yog 70: 30. Dawb granules los yog flakes, melting point 48 ~ 52 degrees.

Vim tias qhov chaw ntawm cov khoom siv raw yog cov nroj tsuag uas muaj cua sov, lub hauv paus chiv keeb feem ntau yog Thaib teb, Philippines, Malaysia thiab lwm lub tebchaws.

Nco tseg:Peb lub tuam txhab kuj muab 50: 50 thiab 30: 70 cov khoom, nrog cov ntsiab lus sib txawv, Yog tias koj muaj kev xav tau rau cetearyl cawv, thov hu rau peb txhua lub sijhawm.
