Methyl 4-chloroacetoacetate

ʻAʻole hiki ke puhi ʻia, loaʻa kahi ala alkyl phenol kūikawā.Hiki ke hoʻoheheʻe ʻia i ka waiʻona, ester, alkane, aromatic a me nā mea hoʻoheheʻe ʻē aʻe, e like me ka ethanol, acetone, butyl acetate, gasoline, toluene, hiki ke hoʻoheheʻe ʻia i ka hopena alkali ikaika.Me nā hiʻohiʻona maʻamau o nā mea phenolic, e pili ana me ka māmā, ka wela, ka hoʻopili ʻana me ka ea, ua hoʻonui ʻia ke kala.

I ka hana ʻoihana, hoʻohana nui ʻia ka p-tert-butylphenol i ka hana ʻana i ka resin soluble phenolic resin, ka inika paʻi, ka lapalapa ahi, etc. Hoʻohana pū ʻia ʻo PTBP ma ke ʻano he polyvinyl chloride stabilizer, surfactant, a me UV absorber.Ma ke kahua o nā mea pili meaʻai, hoʻohana pinepine ʻia ka p-tert-butyl phenol i ka hana ʻana i nā resins polycarbonate, a hiki ke hoʻohana ʻia i ka synthesis o nā mea hoʻohui no nā mea pili meaʻai.

1. Palekana o PTBP
ʻAʻohe mea ʻawaʻawa o ka PTBP, a ʻo ka ʻawaʻawa o ka waha o nā ʻiole me LD50> 2000 mg/kg no ka ʻona haʻahaʻa.Loaʻa iā ia ka huhū haʻahaʻa i ka ʻili rabbit.Uaʻikeʻia ka waiwai NOAEL o 60 mg / kg · bw / lā i kekahi mauʻiole me ka hanuʻino a paʻakikī paha a me ka emiʻana o ka plasma albumin i ka manawa o 42 mau lā waha.I kēia manawa, aia ka PTBP i nā estrogens phenolic exogenous, a ʻo ka waiwai NOAEL o ka ʻawaʻawa reproductive iole ʻo 200 mg / kg · bw / lā, e hōʻike ana i kekahi mau mea ʻawaʻawa hānau.No laila, loaʻa i ka PTBP kekahi mau pilikia a pono e nānā.

2. Hoʻohana i ka PTBP i nā mea pili meaʻai
ʻO ka PTBP he mea kemika i loaʻa ʻole a ʻaʻole i loaʻa i nā mea pili meaʻai.Hiki ke hoʻohana ʻia e like me ka hana polymer a i ʻole additive.
I nā polymers, hoʻohana nui ʻia lākou e like me ka monomer starter a me ka hope-sealing agent.No ka laʻana, ma ka uhi ʻana i nā polymers, formaldehyde, phenol, p-tert-butylphenol polymers a me nā polymers o formaldehyde, phenol, p-tert-butylphenol a me n-butanol polymers me ka p-tert-butylphenol e like me ka monomer a me ka mea hoʻomaka.Poly4,4 '-isopropyl diphenyl carbonate plastics i hoʻopaʻa ʻia me ka p-tert-butylphenol i loko o nā polymers plastic.
Ma ke ʻano he mea hoʻohui, hiki ke hoʻohana ʻia e hōʻemi i ka ʻike o ka end-hydroxyl i nā uhi a hoʻomaikaʻi i ke kūpaʻa o nā huahana.I loko o ka plastic hiki ke hoʻohana 'ia e like me ka antioxidant, e like me ka PS plastic meaʻai pili mea a me nā huahana, i mea e keakea i ka huahana i ka hana a me ka hoʻohana 'ana i ka thermal oxidation, photooxidation reaction speed, lohi degradation, melemele kaʻina kahiko, a hooloihi i ka lawelawe. ola o ka huahana.

He mau waiwai antioxidant ka P-tert-butylphenol a hiki ke hoʻohana ʻia ma ke ʻano he stabilizer no ka lāʻau, kopa, hydrocarbons chlorinated a me nā fiber digestive.Uv absorbent, pesticide, rubber, pena a me kekahi mea anti-cracking agent.No ka laʻana, hoʻohana ʻia no ka resin polycarbon, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.Eia kekahi, ʻo ia hoʻi ka mea maka o ka lāʻau lapaʻau insect repellent, pesticide a me ka acaricide, ʻala a me ka mea mālama mea kanu.Hiki ke hoʻohana ʻia e like me ka softener, solvent, additive of dyes and paints, antioxidant of lubricating oil, oil demulsifier and additive o ka wahie kaʻa.

Nā polokalamu ʻē aʻe:
(1) No ka aila soluble phenolic resin, hiki ke loaʻa ka huahana a me ka formaldehyde condensation no nā kumu like ʻole.I loko o ka chloroprene adhesive i hui pū ʻia me 10-15% o ka huahana, e loaʻa i ka resin soluble, hoʻohana nui ʻia kēia ʻano adhesive i ka halihali, kūkulu, kīwila, hana kāmaʻa, etc. paʻi, kiʻi kiʻi kiʻi kiʻekiʻe a pēlā aku.I ka insulation varnish, hiki ke hoʻohana ʻia i ka coil dip varnish a me ka laminate varnish.
(2) No ka hana polycarbonate, e like me ka phosgene polycarbonate reaction termination agent, e hoʻohui ana i ka helu Chemicalbook o 1-3% o ka resin.
(3) Hoʻohana no ka epoxy resin, xylene resin hoʻololi;E like me ka polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) Me nā waiwai antioxidant, hiki ke hoʻohana ʻia e like me ke kopa, kopa, chlorinated hydrocarbons a me ka nitrocelluloose stabilizer.ʻO ia hoʻi kahi mea maka o ka insect repellent (lāʻau lapaʻau), acaricide acaride (pesticide) a me ka mea hoʻomalu mea kanu, ʻala, resin synthetic, a hiki ke hoʻohana ʻia e like me ka softener, solvent, dye and paint additive.Hiki ke hoʻohana ʻia e like me ke ʻano o ka demulsifier no ka māla aila a me ka mea hoʻohui no ka aila kaʻa.
