Heerka nadiifka sare ee 1,1,3-trichloroacetone diyaarinta

Abstract:acetone catalyzed chloride oo ay soo saartay crystallization dareere ah 1,1,3-trichloroacetone oo leh nadiif sare oo aan ka yarayn 99.0%, oo leh 45% o ereyada muhiimka ah: 1,1,3-trichloroacetone;

----Hordhac

1,1,3■trichloroacetone waa dhex dhexaad muhiim u ah soosaarka folic acid.Waqtigan xaadirka ah,1,1,3.acetone trichloropacetone,wareeg wax soo saar dheer(48saacadood),doorasho liidata,soosaarka hoose,1,1,3- Maaddada trichloropacetone waa kaliya 17%, ka dib marka la soo saaro biyaha, waxa ku jira kaliya 51.9% .iyo qiimaha wax soo saarku waa sarreeyaa, hagaajinta alaabadu waa yar tahay. Dhammaan tani waxay keenaysaa kharashka wax soo saarka folic acid ee gudaha, way adagtahay in la hagaajiyo nuxurka iyo kuwa kale. dhibaatooyin.Tijaabooyin iyo daraasado badan ka dib, waxaanu ku darnay kicinta iyo xakamaynta xawaaraha fou chlorine, yaraynta wakhtiga falcelinta ilaa 1,1,3-3 trichloropacetone 24 saacadood, iyo 1,1,3-3 trichloropacetone crystallization with daahirsanaan ka weyn 99% iyo wax-soo-saarka in ka badan 45%.

1. Talaabooyinka tijaabada ah

Galaas afar luqun ah oo leh koodhiye wareegsan oo 500ml ah, qadar go'an oo acetone ah iyo kicinta ayaa la walaaqay waxaana lagu quudiyay koloriin heerkulka falcelinta ee 10 ~ 30 W. Wakhtiga bilaw, jooji inaad dhex marto koloriin dhowr saacadood ka dib falcelinta, oo sii wad walaaqaya saacada 1. Walxaha gaarka ah ee sida walaxda ayaa lagu daray isku darka ka dhashay, walaaqay 1 saac halka la qaboojiyey 10 ° C crystallization, soo saarista 1,1,3-trichloroacetone.

1. 1,1,3.Go'aaminta xulashada daahirinta trichloroacetone

Varin 3700 gaas chromatograph, QF・ 1 tiirka buuxinta iyo FID detector ayaa loo isticmaalay si loo go'aamiyo faa'iidada nadiifka ah ee alaabta iyo xalka koloriin.

1. Natiijooyinka doodda
2. Saamaynta kicinta ee xulashada koloriintu waxay muujisay xulashada koloriinta acetone

Saamayn weyn, Shaxda 1 waxa ay taxaysaa natiijooyin tijaabo ah oo kala duwan
