Daim ntawv thov
2-Pentadecanone feem ntau yog siv los ua zaub mov ntxiv, tshuaj reagents, tshuaj zoo, tshuaj intermediates thiab cov khoom nruab nrab. Nws yog siv los ua ib qho nruab nrab hauv kev lag luam tshuaj los ua ke ntau yam tshuaj, thiab tseem tuaj yeem siv los ua cov khoom lag luam xws li txuj lom thiab tsw.
Daim ntawv thov ntawm {{0}} pentadecanone nyob rau hauv cov zaub mov teb yog feem ntau xav txog nyob rau hauv nws siv raws li ib tug khoom noj khoom haus additives, tshwj xeeb tshaj yog raws li ib tug zaub mov tsw. 2-pentadecanone raug cais raws li GRAS (feem ntau lees paub tias muaj kev nyab xeeb) cov khoom siv, thiab kev txwv siv los ntawm FEMA yog 75.0mg / kg. Tsis tas li ntawd, raws li GB 2760 tus qauv, kev siv ntawm 2-pentadecanone raws li cov khoom noj qab zib yuav tsum xyuas kom meej tias txhua qhov tsw qab yuav tsum tsis pub tshaj qhov siab tshaj qhov tso cai siv nyiaj thiab qhov siab tshaj plaws tso cai.
Tsis tas li ntawd, 2-pentadecanone tuaj yeem siv los npaj cov khoom qab zib kom muaj cov aroma thiab tsw ntawm cov zaub mov, uas yog tshwj xeeb tshaj yog muaj nyob rau hauv cov khoom noj uas yuav tsum tau tshwj xeeb aromas.
Thaum khaws cia 2-pentadecanone, lub thawv yuav tsum muab kaw thiab khaws cia rau hauv qhov chaw txias, qhuav kom tsis txhob muaj oxides. Hais txog kev pabcuam thawj zaug, yog tias nqus tau, tus neeg mob yuav tsum tau tsiv mus rau huab cua ntshiab, thiab daim tawv nqaij yuav tsum tau muab yaug nrog xab npum thiab dej huv tom qab sib cuag, thiab qhov muag yuav tsum tau yaug nrog dej huv lossis ntsev tom qab kev sib cuag, thiab kev kho mob yuav tsum tau nrhiav tam sim tom qab noj.
Hais txog kev tiv thaiv hluav taws, nws raug nquahu kom siv dej pos huab, hmoov qhuav, ua npuas ncauj lossis carbon dioxide tua hluav taws, thiab tsis txhob siv dej ncaj qha los tua hluav taws los tiv thaiv kev sib kis ntawm hluav taws. Thaum lub sijhawm ua haujlwm thiab muab pov tseg, tsis txhob sib cuag nrog lub qhov muag thiab tawv nqaij, nyob deb ntawm qhov hluav taws kub thiab cua sov, thiab siv cov tshuab ua pa thiab cov khoom siv tawg.
