1,1,3■trichloroacetone waa dhexdhexaad 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 badeecadu waa yar tahay. Dhammaantood waxay keenaan kharashka wax soo saarka folic acid ee gudaha, 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 saar ka badan 45%.

1. Talaabooyinka tijaabada ah

Galaas afar luqun ah oo leh kondenser spherical 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 sida walxaha 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 koloriinta.

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

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

　　Xakamaynta amine-ka ee isku dhafan ayaa ah kan ugu fiican, ilaa 57.5%

1. Saamaynta xawaaraha koloriinta ee falcelinta

Tijaabadu waxay ogaatay in koloriin isku mid ah ay leedahay xulashada wax soo saarka liidata, taasoo si weyn u wanaajisay xulashada wax soo saarka iyo wax-soosaarka.

Shaxda 2 ayaa taxaysa xogta tijaabada ah.

Shaxda 2 Saamaynta xawaaraha koloriinta-dhaafka ee xulashada wax soo saarka

Tijaabada ^ xaalad:] Petri saxan 1 acetone, kicinta: class composite 0.6go

Tijaabadu waxay ogaatay in fluchlorine ay ahayd xilli hore (12 saacadood) iyo ka dib (8 24 saacadood), badiyaa koloriintu waxay ka baxsatay in falcelintu ay gaabis ahayd dhexdhexaadkuna (28 saacadood) uu ahaa mid degdeg ah.Marka gaaska chlorine la joojiyo, xulashada wax soo saarka iyo soo saarista Natiijooyinku waxay muujiyeen in 1,1,3 ay soo saareen wax aad uga hooseeya

Qoraagu waxa uu rumaysan yahay in habka falcelinta jiilka acetone chloride uu yahay:

Falcelinta waxaa lagu sameeyaa V1 1 2-5 habka ugu muhiimsan.

Marka loo eego xogta shaxda 2, nidaamka xawaaraha falcelinta ee tillaabo kasta waa

　　V2^”3^1 2 5>V4

Iyadoo ku xiran xawaaraha falcelinta ee tallaabo kasta,

Waxaa laga arki karaa xogta Shaxda 3, sababtoo ah farqi yar oo karkaraya farqiga u dhexeeya 1,1,3.trichloroacetone iyo by-products, guud ahaan way adagtahay in la kala saaro soo saarista biyaha iyo kala-soocidda waa macne fudud. Inkastoo inta badan I alaabta waa laga saari karaa, daahirsanaanta waa adag tahay

waxaan xakameynaa xawaaraha koloriinta ee dhaafitaanka marxalad kasta,

si loo gaaro ujeedada dhimista wakhtiga koloriinta ee dhaafka iyo joojinta xulashada kordhinta xawaaraha falcelinta labaad ee 1,1,3 trichloroacetone.

1. Nadiifinta kareemka oo biyo leh Sida laga soo xigtay suugaanta, inta badan

dareeraha chloride acetone ayaa laga soosaaraa ama lagu sifeeyaa biyo si loo kordhiyo waxa ku jira 1,1,3-trichloroacetone, qoraagu waxa uu 1,1,3-trichloroacetone u adeegsaday crystallization from-products.

Shaxda 3 ayaa taxaysa nadiifnimada alaabta ee lagu helay hababka kala duwan ee kala duwan.

Shaxda 3. Nadiifinta badeecada ee laga helay hababka kala duwan ee kala duwan

Si loo sii wanaajiyo. Nadaafadda badeecadu waxay gaartaa in ka badan 99%, wax-soo-saarku sidoo kale waa kan ugu sarreeya dhowr habab, ilaa 45% o.1 Habka wuxuu u baahan yahay 1,1,3-trichloroacetone content of K in ka badan 50% koloriinta xal.

Dooro kicinta amine ee ku habboon, xakamee xannibaadda koloriinta tartiib tartiib ah ee horraantii iyo dabayaaqadii 10 ~ 30 ° C, waxay samayn kartaa 1,1,3-trichloroacetone chloride, oo lagu nadiifiyo crystallization dareere gaar ah, hel badeeco crystalline ah oo aan ka yarayn 99.0%, oo leh wax soo saar of 45%, laakiin 1,1,3-trichloroacetone ee xalka koloriinku waa inuu ka weynaadaa 50% o.Agaasimaha guud ee Athena
