Phenylacetyl Chloride
Kusunga m'nyumba yozizira, youma ndi bwino mpweya wosungiramo katundu.Khalani kutali ndi moto ndi gwero la kutentha.Phukusili liyenera kukhala losindikizidwa komanso lopanda chinyezi.Iyenera kusungidwa mosiyana ndi oxidant, alkali ndi mankhwala odyedwa, ndipo kusungidwa kosakanikirana kuyenera kupewedwa.Zida zozimira moto zamitundu yosiyanasiyana komanso kuchuluka kwake zidzaperekedwa.Malo osungiramo zinthu adzakhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zosungirako.
-
P-cresol
Izi ndizopangira zopangira antioxidant 2,6-di-tert-butyl-p-cresol ndi rabara antioxidant.Nthawi yomweyo, ndizofunikanso zopangira zopangira mankhwala a TMP ndi utoto wa coricetin sulfonic acid.1. GB 2760-1996 ndi mtundu wa zonunkhira zomwe zimaloledwa kugwiritsidwa ntchito.
-
P-tolonitrile
Njira zopewera mayendedwe: Musananyamuke, yang'anani ngati chotengeracho chatha ndikusindikizidwa, ndikuwonetsetsa kuti chidebecho sichikutha, kugwa, kugwa kapena kuwonongeka panthawi yamayendedwe.Ndizoletsedwa kusakaniza ndi ma asidi, okosijeni, chakudya ndi zowonjezera zakudya.
-
P-toluic Acid
Imakonzedwa ndi catalytic oxidation ya p-xylene ndi mpweya.Mukamagwiritsa ntchito njira yamphamvu ya mumlengalenga, xylene ndi cobalt naphthenate zimatha kuwonjezeredwa mumphika wochitirapo kanthu, ndipo mpweya umayambitsidwa potentha mpaka 90 ℃.Kutentha kwamachitidwe kumayendetsedwa pa 110-115 ℃ pafupifupi maola 24, ndipo pafupifupi 5% ya p-xylene imasinthidwa kukhala p-methylbenzoic acid.
-
4-(Chloromethyl)Tolunitrile
Pakati pa pyrimethamine.Amagwiritsidwa ntchito popanga p-chlorobenzyl mowa;p-chlorobenzaldehyde;p-chlorobenzene acetonitrile, etc.
-
4-tert-butylphenol
P-tert-butylphenol ali ndi antioxidant katundu ndipo angagwiritsidwe ntchito ngati stabilizer kwa labala, sopo, chlorinated hydrocarbons ndi ulusi digested.Ma UV absorbers, anti-cracking agents monga mankhwala ophera tizilombo, mphira, utoto, etc. Mwachitsanzo, amagwiritsidwa ntchito ngati stabilizer ya polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, ndi styrene.
-
2,4,6-Trimethylaniline
2,4,6-Trimethylaniline ndi yapakatikati yomwe imagwiritsidwa ntchito kwambiri mu utoto, mankhwala ophera tizilombo ndi mafakitale ena.Zopangira zopangira mesitidine ndi mesitylene, yomwe imapezeka mu petroleum.Pozindikira kupanga mafakitale akuluakulu ku China, kutulutsa kwa mesitylene kwapitirizabe kuwonjezeka, kotero kuti chitukuko cha zinthu zake zotsika pansi chalandira chidwi kwambiri.
-
4,4′-Bis(chloromethyl)-1,1′-Biphenyl
Chinsinsi chapakatikati pa kaphatikizidwe ka biphenyl bisphenylacetylene fulorosenti whitening wothandizira CBS-X ndi CBS-127.Itha kugwiritsidwanso ntchito ngati mankhwala kapena utomoni wapakatikati.
