High-purity level ye1,1,3-trichloroacetone kugadzirira

Abstract:acetone catalyzed chloride uye inogadzirwa ne solvent crystallization pa1,1,3-trichloroacetone ine hutsanana hwepamusoro husingasviki 99.0%,ine goho re45%o Mazwi akakosha:1,1,3-trichloroacetone;synthesis;kuchena kwakanyanya

-----------.Nhanganyaya

1,1,3■trichloroacetone inokosha yepakati mukugadzirwa kwefolic acid.Parizvino,1,1,3.acetone trichlorropacetone,kurebesa kwekugadzirwa kwemaawa(48 maawa),kusaita zvakanaka,goho rakaderera,1,1,3- trichlorropacetone content inongosvika 17%,mushure mekudzurwa kwemvura,zvirimo i51.9% chete.Uye mutengo wekugadzira wakakwira,chigadzirwa chekugadzirisa chakaderera.Izvi zvese zvinotungamira kumitengo yepamusoro yekugadzira folic acid yemumba,inonetsa kuvandudza zvirimo nezvimwe. matambudziko.Munyori akaverenga nhamba huru yemagwaro epamba neekunze.Mushure mekuedza kwakawanda uye zvidzidzo, takawedzera catalyst uye kudzora fou chlorine kumhanya, kuderedza nguva yekuita kusvika ku1,1,3-3 trichlorropacetone mumaawa makumi maviri nemana, uye 1,1,3-3 trichlorropacetone crystallization nekuchena kukuru kupfuura 99% uye goho rinodarika 45%.

Mubhodhoro remitsipa mina rine 500ml spherical condenser, imwe acetone uye catalyst yakamutswa uye yakadyiswa ku chlorine painodziya tembiricha ye10 ~ 30 W. Tanga nguva, rega kupfuura nemuklorini maawa akawanda mushure mekuita, uye enderera mberi. kubvongodza kweawa 1. Mushonga unokosha wakafanana nezvinhu wakawedzerwa kumusanganiswa unoguma, wakasvetwa kweawa imwe uchitonhorera kusvika ku10 ° C crystallization, kubvisa 1,1,3-trichloroacetone.

1. 1,1,3.Kusarudza kusarudzwa kwe trichloroacetone kuchena

Varin 3700 gasi chromatograph, QF ・ 1 mbiru yekuzadza uye FID detector yakashandiswa kusarudza kuchena purofiti yechigadzirwa uye chloride mhinduro.

1. Migumisiro yehurukuro
2. Pesvedzero yecatalyst pane chloride selectivity yakaratidza kusarudzwa kweacetone chlorination

Kurudziro huru, Tafura 1 inoronga seti yezviyedzo zvabuda.Kubva Tafura 1, kushoma kusarudzwa kwe1,1,3-trichloroacetone kunowedzerwa zvakanyanya (inenge 19.1%) pasina catalyst, uye
