Methyl 4-chloroacetoacetate

Flammable amma ba mai ƙonewa ba, yana da warin alkyl phenol na musamman.Soluble a barasa, ester, alkane, aromatic da sauran kwayoyin kaushi, irin su ethanol, acetone, butyl acetate, fetur, toluene, mai narkewa a cikin karfi alkali bayani.Tare da halaye na yau da kullun na abubuwan phenolic, a cikin hulɗa da haske, zafi, lamba tare da iska, launi ya zurfafa a hankali.

A masana'antu samar, p-tert-butylphenol ne yafi amfani a samar da man mai soluble phenolic guduro, bugu tawada, harshen wuta retardant, da dai sauransu PTBP kuma ana amfani da a matsayin polyvinyl chloride stabilizer, surfactant, kuma UV absorber.A fagen kayan tuntuɓar abinci, ana amfani da p-tert-butyl phenol sau da yawa a cikin samar da resins na polycarbonate, kuma ana iya amfani dashi a cikin haɗakar abubuwan ƙari don kayan hulɗar abinci.

1. Tsaro na PTBP
PTBP ba shi da cututtukan ƙwayoyin cuta da ƙwayoyin cuta na carcinogenic, kuma tsananin guba na baki na berayen tare da LD50> 2000 mg/kg na da ƙarancin guba.Yana da matsakaicin haushi ga fatar zomo.An lura da ƙimar NOAEL na 60 mg/kg·bw/rana a cikin wasu berayen tare da rashin al'ada ko wahalar numfashi da raguwar albumin plasma yayin maimaita baki na kwanaki 42.A halin yanzu, PTBP na cikin exogenous phenolic estrogens, kuma NOAEL darajar bera gubar haihuwa shine 200 mg/kg·bw/rana, yana nuna wasu gubar haihuwa.Saboda haka, PTBP yana da wasu haɗari kuma ya cancanci kulawa.

2. Aikace-aikacen PTBP a cikin kayan hulɗar abinci
PTBP wani nau'in sinadari ne wanda baya samuwa ko babu a cikin kayan tuntuɓar abinci.Ana iya amfani dashi azaman samar da polymer ko ƙari.
A cikin polymers, ana amfani da su galibi azaman mai farawa na monomer da wakili na ƙarshe.Alal misali, a cikin rufi na tushen polymers, formaldehyde, phenol, p-tert-butylphenol polymers da polymers na formaldehyde, phenol, p-tert-butylphenol da n-butanol polymers tare da p-tert-butylphenol a matsayin monomer da Starter.Poly4,4 '-isopropyl diphenyl carbonate robobi da aka hatimce da p-tert-butylphenol a cikin polymers filastik.
A matsayin ƙari, ana iya amfani dashi don rage abun ciki na ƙarshen-hydroxyl a cikin sutura da inganta kwanciyar hankali na samfurori.A cikin filastik ana iya amfani da shi azaman antioxidant, kamar kayan haɗin abinci na filastik PS da samfuran, don hana samfurin a samarwa ko amfani da iskar shakawar thermal, saurin amsawar photooxidation, lalatawar jinkiri, tsarin tsufa na rawaya, da tsawaita sabis. rayuwar samfurin.

P-tert-butylphenol yana da kaddarorin antioxidant kuma ana iya amfani dashi azaman stabilizer don roba, sabulu, chlorinated hydrocarbons da fiber na narkewa.Uv absorbent, magungunan kashe qwari, roba, fenti da sauran magungunan hana fatattaka.Alal misali, ana amfani da shi don guduro polycarbon, tert-butyl phenolic guduro, epoxy guduro, polyvinyl chloride, styrene stabilizer.Bugu da kari, shi ne kuma albarkatun kasa na Pharmaceutical maganin kwari, magungunan kashe qwari da acaricide, kamshi da shuka kare wakili.Hakanan za'a iya amfani dashi azaman softener, sauran ƙarfi, ƙari na dyes da fenti, antioxidant na mai mai mai, mai lalata mai da ƙari na man abin hawa.

Sauran aikace-aikace:
(1) Don resin phenolic mai mai narkewa, ana iya samun samfur da kwarin gwiwar formaldehyde don dalilai iri-iri.A cikin chloroprene m gauraye 10-15% na samfurin, don samun mai soluble guduro, irin wannan m ne yafi amfani a harkokin sufuri, yi, farar hula, takalma-yin, da dai sauransu A bugu tawada, za a iya amfani da rosin gyare-gyare, biya diyya. bugu, manyan hotuna da sauransu.A cikin nau'i na nau'i na nau'i na nau'i, ana iya amfani dashi a cikin laminate varnish.
(2) Don samar da polycarbonate, azaman wakili mai ƙarewa na phosgene polycarbonate, ƙara adadin littafin Chemical na 1-3% na guduro.
(3) An yi amfani da shi don resin epoxy, xylene resin gyare-gyare;Kamar yadda polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) Tare da kaddarorin antioxidant, ana iya amfani da su azaman roba, sabulu, chlorinated hydrocarbons da nitrocelluloose stabilizer.Har ila yau, danye ne na maganin kwari (magani), acaricide acaride (pesticide) da wakili na kare tsire-tsire, ƙamshi, guduro na roba, kuma ana iya amfani dashi azaman mai laushi, mai narkewa, rini da ƙari na fenti.Hakanan za'a iya amfani dashi azaman sinadari na demulsifier don filin mai da ƙari ga mai abin hawa.
