Chidule chachidule cha p-tert-butylphenol

P-tert-butyl phenol white crystal, yoyaka, yokhala ndi fungo la phenol pang'ono.Malo osungunuka 98-101 ℃, otentha 236-238 ℃, 114 ℃ (1.33kPa), kachulukidwe wachibale 0.908 (80/4 ℃), refractive index 1.4787.Kusungunuka mu acetone, benzene, methanol, kusungunuka pang'ono m'madzi.Ikhoza kusanduka nthunzi ndi mpweya wa madzi.

Kukonzekera kwa p-tert-butylphenol 1. Amakonzedwa kuchokera ku phenol ndi isobutene ndi cation exchange resin monga chothandizira.2. Okonzeka ndi zochita za phenol ndi diisobutene.Kuphatikiza pa tert-butylphenol, p-octylphenol imapangidwanso mumayendedwe.3. Chomalizidwacho chinapezedwa ndi momwe phenol ndi tert-butanol amachitira pambuyo pochapa, crystallization, centrifugal kupatukana ndi kuyanika.

Kugwiritsa ntchito p-tert-butyl phenol 1. Amagwiritsidwa ntchito mu mafuta osungunuka a phenolic resin, ndi formaldehyde condensation angapeze ntchito zosiyanasiyana za mankhwala.Mu zomatira chloroprene osakaniza 10-15% ya mankhwala, kupeza sungunuka utomoni, zomatira mtundu uwu makamaka ntchito zoyendera, zomangamanga, boma, kupanga nsapato, etc. kusindikiza, photogravure zapamwamba ndi zina zotero.Mu kutchinjiriza varnish, angagwiritsidwe ntchito koyilo kuviika varnish ndi laminate varnish.2. Ntchito kupanga polycarbonate, monga phosgene polycarbonate anachita kuthetsa wothandizila, kuwonjezera kuchuluka kwa 1-3% ya utomoni.3. Amagwiritsidwa ntchito pa epoxy resin, xylene resin resin;Monga polyvinyl chloride stabilizer, surfactant, UV absorber.4. Imakhala ndi antioxidant katundu ndipo ingagwiritsidwe ntchito ngati stabilizer ya rabara, sopo, chlorinated hydrocarbons ndi nitrocelluloses.Ndiwopangira mankhwala othamangitsa tizilombo (mankhwala), acaricide acaride (mankhwala ophera tizilombo) ndi woteteza mbewu, kununkhira, utomoni wopangira, komanso angagwiritsidwe ntchito ngati zofewa, zosungunulira, utoto ndi zowonjezera utoto.Itha kugwiritsidwanso ntchito ngati chophatikizira cha demulsifier pamunda wamafuta komanso chowonjezera chamafuta amgalimoto.
