Kusungunuka: Kusungunuka mosavuta mu zosungunulira za organic monga mowa, esters, alkanes, ma hydrocarbon onunkhira, monga ethanol, acetone, butyl acetate, mafuta, toluene, ndi zina zotero. Zosungunuka pang'ono m'madzi, zimasungunuka muzitsulo zamphamvu zamchere.
Kukhazikika: Izi zimakhala ndi mawonekedwe a phenolic zinthu.Mukakumana ndi kuwala, kutentha, kapena mpweya, mtunduwo umazama pang’onopang’ono.
Main Application
P-tert-butylphenol ali ndi antioxidant katundu ndipo angagwiritsidwe ntchito ngati stabilizer kwa labala, sopo, chlorinated hydrocarbons ndi ulusi digested.Ma UV absorbers, anti-cracking agents monga mankhwala ophera tizilombo, mphira, utoto, etc. Mwachitsanzo, amagwiritsidwa ntchito ngati stabilizer ya polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, ndi styrene.Kuphatikiza apo, ndizinthu zopangira zopangira mankhwala othamangitsa tizilombo, Kmitt mankhwala ophera tizilombo, zonunkhira ndi zoteteza zomera.Itha kugwiritsidwanso ntchito monga zofewa, zosungunulira, zowonjezera utoto ndi utoto, zoteteza ku mafuta opaka mafuta, zochotsera mafuta m'minda yamafuta ndi zowonjezera pamafuta agalimoto.
Njira Yopangira
Pali njira zinayi zopangira tert-butyl phenol:
(1) Njira ya Phenol isobutylene: gwiritsani ntchito phenol ndi isobutylene monga zopangira, cation exchange resin monga chothandizira, ndikuchita alkylation reaction pa 110 ° C pansi pa mphamvu yachibadwa, ndipo mankhwalawa akhoza kupezedwa ndi distillation pansi pa kupanikizika kochepa;
(2) Phenol diisobutylene njira;pogwiritsa ntchito silicon-aluminium chothandizira, pa mphamvu ya 2.0MPa, kutentha kwa 200 ° C, ndi njira yamadzimadzi, p-tert-butylphenol imapezeka, komanso p-octylphenol ndi o-tert-butylphenol.Zomwe zimapangidwira zimapatulidwa kuti zipeze p-tert-butylphenol;
(3) C4 kachigawo kakang'ono: pogwiritsa ntchito kachigawo kakang'ono ka C4 ndi phenol monga zopangira, pogwiritsa ntchito titaniyamu-molybdenum oxide monga chothandizira, zomwe zimapeza chisakanizo cha phenol alkylation reaction ndi p-tert-butylphenol monga chigawo chachikulu, ndipo mankhwala ndi anapezedwa pambuyo kulekana;
(4) Phosphoric acid chothandizira njira: phenol ndi tert-butanol amagwiritsidwa ntchito ngati zopangira, ndipo mankhwalawa angapezeke mwa kuchapa ndi kupatukana kwa crystallization.
[Unyolo wa mafakitale] Isobutylene, tert-butanol, phenol, p-tert-butylphenol, antioxidants, stabilizers, mankhwala, mankhwala ophera tizilombo ndi zinthu zina zopangira organic.
Kuyika, Kusungirako ndi Mayendedwe
Imadzaza ndi filimu ya polypropylene yokhala ndi thumba la pepala lopanda kuwala ngati mawonekedwe akunja, ndi ng'oma yolimba ya makatoni.25kg / drum.Sungani m'nyumba yosungiramo zozizira, mpweya wokwanira, wowuma komanso wamdima.Osayiyika pafupi ndi mapaipi amadzi ndi zida zotenthetsera kuti mupewe chinyontho ndi kuwonongeka kwa kutentha.Khalani kutali ndi moto, kutentha, okosijeni, ndi chakudya.Zida zoyendera ziyenera kukhala zaukhondo, zouma, komanso kupewa kuwala kwa dzuwa ndi mvula panthawi yoyenda.
