Kuyeretsa kwakukulu kwa kukonzekera kwa 1,1,3-trichloroacetone

Zachidziwikire:acetone catalyzed chloride ndipo amapangidwa ndi zosungunulira crystallization pa 1,1,3-trichloroacetone yokhala ndi chiyero chosachepera 99.0%,ndi zokolola za 45%o Mawu ofunika:1,1,3-trichloroacetone;kaphatikizidwe;kuyera kwakukulu

----------.Mawu oyamba

1,1,3■ trichloroacetone ndi yofunika yapakatikati pakupanga folic acid.Pakali pano,1,1,3.acetone trichlorropacetone,utali wa kupanga (maola 48),kusasankha bwino,zokolola zochepa,1,1,3- trichlorropacetone zili pafupifupi 17%, pambuyo m'zigawo madzi, zomwe zili ndi 51.9% yokha.Ndipo mtengo kupanga ndi mkulu, mankhwala kukonza ndi low.These kumabweretsa mkulu zoweta kupatsidwa folic acid kupanga ndalama, zovuta kusintha zili ndi zina. mavuto.Wolembayo adawerenga zolemba zambiri zapakhomo ndi zakunja.Pambuyo kuyesera ndi maphunziro ambiri, ife anawonjezera chothandizira ndi kulamulira fou chlorine liwiro, kuchepetsa anachita nthawi 1,1,3-3 trichlorropacetone mu maola 24, ndi 1,1,3-3 trichlorropacetone crystallization ndi chiyero kuposa 99% ndi zokolola zoposa 45%.

Mu botolo la khosi linai lokhala ndi 500ml spherical condenser, kuchuluka kwa acetone ndi chothandizira zinagwedezeka ndi kudyetsedwa ku klorini pa kutentha kwa 10 ~ 30 W. Yambani nthawi, siyani kudutsa chlorine maola angapo pambuyo pake, ndipo pitirizani. kuyambitsa kwa ola la 1. Chosungunulira chapadera ngati zinthu chinawonjezeredwa ku chisakanizocho, chokhazikika kwa ola la 1 pamene utakhazikika ku 10 ° C crystallization, kuchotsa 1,1,3-trichloroacetone.

Chikoka chachikulu, Gulu 1 limatchula zotsatira zoyesera. Kuchokera pa Table 1, kusankha kochepa kwa 1,1,3-trichloroacetone kumawonjezeka kwambiri (pafupifupi 19.1%) popanda chothandizira, ndipo
