P-tert-butyl phenol dawb crystal, flammable, nrog me ntsis phenol tsw.Melting point 98-101 ℃, boiling point 236-238 ℃, 114 ℃ (1.33kPa), txheeb ze ceev 0.908 (80/4 ℃), refractive index 1.4787.Soluble hauv acetone, benzene, methanol, me ntsis soluble hauv dej.Yuav evaporate nrog dej vapor.
Kev npaj ntawm p-tert-butylphenol 1. Nws yog npaj los ntawm phenol thiab isobutene nrog cation exchange resin ua catalyst.2. Npaj los ntawm cov tshuaj tiv thaiv ntawm phenol nrog diisobutene.Ntxiv nrog rau tert-butylphenol, p-octylphenol kuj tsim nyob rau hauv cov txheej txheem tshuaj tiv thaiv.3. Cov khoom tiav tau txais los ntawm cov tshuaj tiv thaiv ntawm phenol thiab tert-butanol tom qab ntxuav, crystallization, centrifugal sib cais thiab ziab.
Kev siv p-tert-butyl phenol 1. Siv cov roj soluble phenolic resin, thiab formaldehyde condensation tuaj yeem tau txais ntau yam kev siv ntawm cov khoom.Nyob rau hauv chloroprene nplaum sib tov 10-15% ntawm cov khoom, kom tau soluble resin, hom nplaum no tsuas yog siv rau hauv kev thauj mus los, kev tsim kho, pej xeem, khau-ua, thiab lwm yam hauv kev luam ntawv number case, tuaj yeem siv rau kev hloov kho rosin, offset. printing, advanced photogravure thiab hais txog.Nyob rau hauv lub rwb thaiv tsev varnish, yuav siv tau nyob rau hauv coil dip varnish thiab laminate varnish.2. Siv rau polycarbonate ntau lawm, raws li phosgene polycarbonate cov tshuaj tiv thaiv termination tus neeg saib xyuas, ntxiv tus nqi ntawm 1-3% ntawm resin.3. Siv rau epoxy resin, xylene resin hloov kho;Raws li polyvinyl chloride stabilizer, surfactant, UV absorber.4. Nws muaj cov khoom antioxidant thiab tuaj yeem siv los ua kom ruaj khov rau roj hmab, xab npum, chlorinated hydrocarbons thiab nitrocelluloses.Nws tseem yog cov khoom siv raw ntawm cov tshuaj tua kab (tshuaj), acaricide acaride (tshuaj tua kab) thiab cov nroj tsuag tiv thaiv, tshuaj tsw qab, hluavtaws cob, thiab tseem tuaj yeem siv ua softener, hnyav, dye thiab xim additive.Nws kuj tseem siv tau los ua cov khoom xyaw ntawm demulsifier rau roj teb thiab ntxiv rau cov roj tsheb.
