Uburyo bwo kubyaza umusaruro
1. Kubona okiside ya catalitiki ya o-xylene.Gukoresha o-xylene nkibikoresho fatizo na cobalt naphthenate nka catalizator, ku bushyuhe bwa 120 ° C hamwe n’umuvuduko wa 0.245 MPa, o-xylene ikomeza kwinjira mu munara wa okiside kugira ngo umwuka wa okiside uhumeke, naho amazi ya okiside yinjira mu minara yambura umunwa wa Chemicalbook. yo kwibanda, korohereza, hamwe na centrifugation.Shaka ibicuruzwa byuzuye.Inzoga z'ababyeyi zirashishwa kugirango zigarure o-xylene hamwe na acide o-toluic, hanyuma zisohore ibisigara.Umusaruro wari 74%.Buri toni y'ibicuruzwa ikoresha kg 1,300 ya o-xylene (95%).
2. Uburyo bwo gutegura ni uko o-xylene idahwema guhumeka umwuka hamwe na catisale ya cobalt naphthenate ku bushyuhe bwa dogere 120-125 ° C hamwe n’umuvuduko wa 196-392 kPa mu munara wa okiside kugirango ubone ibyarangiye ibicuruzwa.
Imikoreshereze y'ibicuruzwa
Imikoreshereze ikoreshwa cyane cyane muguhuza imiti yica udukoko, imiti nibikoresho fatizo bya chimique.Kugeza ubu, ni ibikoresho by'ibanze bikomoka ku bimera.Gukoresha o-methylbenzoic aside ni fungiside pyrrolidone, fenoxystrobin, trifloxystrobin na herbicide benzyl Abahuza sulfuron-methyl barashobora gukoreshwa nkumuhuza wa synthèse organisme nka pesticide bactericide phosphoramide, parfum, vinyl chloride polymerisation MBPO, m-cres utegura firime nibindi.
