Methyl 4-chloroacetoacetate

E mu ae le mu, e iai se manogi fa'apitoa ole alkyl phenol.Soluble i le ava malosi, ester, alkane, aromatic ma isi solvents organic, e pei o le ethanol, acetone, butyl acetate, penisini, toluene, soluble i le malosi alkali solution.Faatasi ai ma uiga masani o mea phenolic, faʻafesoʻotaʻi ma le malamalama, vevela, faʻafesoʻotaʻi ma le ea, lanu faasolosolo faʻalolotoina.

I le gaosiga o fale gaosi oloa, o le p-tert-butylphenol e masani ona faʻaaogaina i le gaosiga o le suauʻu soluble phenolic resin, lomitusi vaitusi, mumu mumu, ma isi. PTBP e faʻaaogaina foi e avea o se polyvinyl chloride stabilizer, surfactant, ma UV absorber.I le fanua o meaʻai faʻafesoʻotaʻi meaʻai, p-tert-butyl phenol e masani ona faʻaaogaina i le gaosiga o polycarbonate resins, ma e mafai foi ona faʻaaogaina i le tuʻufaʻatasia o mea faʻaopoopo mo mea faʻafesoʻotaʻi meaʻai.

1. Puipuiga ole PTBP
O le PTBP e leai se fa'ama'i fa'ama'i ma fa'ama'i, ma o le o'ona tu'u gutu o isumu fa'atasi ma le LD50 > 2000 mg/kg e maualalo le o'ona.E feololo le ita i le pa'u lapiti.O le NOAEL tau o le 60 mg / kg · bw / aso na matauina i nisi o isumu e le masani pe faigata le manava ma faʻaititia le plasma albumin i le taimi o le 42-aso toe fai tautala.I le taimi nei, o le PTBP o loʻo aʻafia i le estrogens phenolic exogenous, ma o le NOAEL tau o le faʻamaʻiina o le iole o le 200 mg / kg · bw / aso, e faʻaalia ai ni faʻamaʻi oona.O le mea lea, o le PTBP e iai ni a'afiaga ma e tatau ona fa'alogoina.

2. Fa'aogaina o le PTBP i mea e fa'afeso'ota'i ai mea'ai
O le PTBP ose vaila'au mata'utia e le o maua pe leai foi i mea'ai e fa'afeso'ota'i ai mea'ai.E mafai ona faʻaaogaina e pei o le gaosiga o polymer poʻo se faʻaopoopoga.
I polymers, e masani ona faʻaaogaina e fai ma monomer starter ma faʻamaufaʻailoga faʻamau.Mo se faʻataʻitaʻiga, i le faʻapipiʻiina o polymers, formaldehyde, phenol, p-tert-butylphenol polymers ma polymers o formaldehyde, phenol, p-tert-butylphenol ma le n-butanol polymers ma p-tert-butylphenol e pei o le monomer ma le starter.Poly4,4 '-isopropyl diphenyl carbonate palasitika fa'amaufa'ailoga i le p-tert-butylphenol i polymers palasitika.
I le avea ai o se faʻaopoopoga, e mafai ona faʻaaogaina e faʻaitiitia ai mea o loʻo i totonu o le end-hydroxyl i coatings ma faʻaleleia le mautu o oloa.I totonu o le palasitika e mafai ona faʻaaogaina e avea o se antioxidant, e pei o PS meaʻai palasitika faʻafesoʻotaʻi meaʻai ma oloa, ina ia faʻalavelaveina le oloa i le gaosiga poʻo le faʻaogaina o le faʻamaʻiina o le vevela, faʻavavega o le photooxidation, faʻatuai le faʻaleagaina, faʻagasologa o le matua samasama, ma faʻaumi le auaunaga. ola o le oloa.

O le P-tert-butylphenol o lo'o i ai mea fa'aantioxidant ma e mafai ona fa'aoga e fai ma fa'amautu mo pa'u, fasimoli, chlorinated hydrocarbons ma alava mea'ai.Uv absorbent, vailaau e tineia ai manu faalafua, pa'u, vali ma isi mea e tete'e ta'e.Mo se faʻataʻitaʻiga, faʻaaogaina mo polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.E le gata i lea, o le mea faʻapitoa foʻi o vailaʻau faʻamaʻi iniseti, vailaau faʻasaina ma acaricide, manogi ma mea e puipuia ai laau.E mafai foʻi ona faʻaaogaina e fai ma faʻamaluluina, solvent, faʻapipiʻi o vali ma vali, antioxidant o le suauu lubricating, suauʻu demulsifier ma faʻaopoopoga o suauu taʻavale.

Isi talosaga:
(1) Mo le suauʻu soluble phenolic resin, le oloa ma formaldehyde condensation e mafai ona maua mo le tele o faamoemoega.I totonu o le chloroprene adhesive fefiloi 10-15% o le oloa, ina ia maua soluble resin, o lenei ituaiga o pipii e masani ona faʻaaogaina i felauaiga, fausiaina, tagata lautele, faia o seevae, ma isi. lomitusi, ata maualuluga ma isi.I totonu o le insulation varnish, e mafai ona faʻaaogaina i le coil dip varnish ma laminate varnish.
(2) Mo le gaosiga o le polycarbonate, e pei o le phosgene polycarbonate fa'agata fa'agata, fa'aopoopo le aofa'i ole tusi ole vaila'au ole 1-3% ole resini.
(3) Faʻaaogaina mo epoxy resin, xylene resin suiga;E pei o le polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) Faatasi ai ma meatotino antioxidant, e mafai ona faaaogaina e pei o le paʻu, fasimoli, chlorinated hydrocarbons ma nitrocelluloose stabilizer.O se mea mataʻutia foʻi o le faʻafefe o iniseti (vailaau), acaricide acaride (pesticide) ma le mea e puipuia ai laau, manogi, resini gaosia, ma e mafai foi ona faʻaaogaina e fai ma faʻamalulu, solvent, vali ma faʻapipiʻi vali.E mafai foi ona faʻaaogaina e fai ma mea e faʻaaogaina ai le demulsifier mo le suauʻu fanua ma faʻaopoopoga mo le suauu taʻavale.
