Habka wax soo saarka
1. Waxaa lagu helay oksaydhdheynta catalytic ee o-xylene.Isticmaalka o-xylene sida walxo ceeriin ah iyo naphthenate cobalt sida kicinta, heerkulka 120 ° C iyo cadaadiska 0.245 MPa, o-xylene waxay si joogto ah u gashaa munaaradda oksaydhka ee hawada oksaydhka ah, dareeraha oksaydhkana wuxuu galaa munaaradda xoqida buug-gacmeedka fiirsashada, crystallization, iyo centrifugation.Hel badeecada dhammaatay.Khamriga hooyadu waa la nadiifiyaa si ay u soo kabsato o-xylene iyo qayb ka mid ah o-toluic acid, ka dibna la sii daayo hadhaaga.Wax-soo-saarku wuxuu ahaa 74%.Tan kasta oo badeeco ah waxay isticmaashaa 1,300 kg oo o-xylene ah (95%).
2. Habka diyaarinta ayaa ah in o-xylene ay si joogto ah oksijiinta hawada ku jirto joogitaanka naphthenate cobalt ee heerkulka falcelinta ee 120-125 ° C iyo cadaadiska 196-392 kPa ee munaarad oxidation ah si loo helo dhammaystiran. alaabta.
Isticmaalka Alaabta
Isticmaalka waxaa inta badan loo isticmaalaa isku dhafka sunta cayayaanka, daawooyinka iyo alaabta ceeriin ee kiimiko ah.Waqtigan xaadirka ah, waa alaabta ceeriin ee ugu weyn ee soo saarista herbicides.Isticmaalka o-methylbenzoic acid waa fungicide pyrrolidone, fenoxystrobin, trifloxystrobin iyo herbicide benzyl Dhexdhexaadiyeyaasha sulfuron-methyl waxaa loo isticmaali karaa sida dhexdhexaadinta organic sida fosphoramide bakteeriyada cayayaanka, cadarka, vinyl chloride polymerization curiyaha midabka MBPO, m- soo saare filimada iyo wixii la mid ah.
