Te taumata parakore teitei o te whakarite 1,1,3-trichloroacetone

Tuhinga: acetone catalyzed pūhaumāota me te whakaputa i te whakarewa whātioatanga i 1,1,3-trichloroacetone me te parakore teitei o te kore iti iho i te 99.0%, me te tuku o te 45%o Kupu matua: 1,1,3-trichloroacetone; te whakahiato; te parakore teitei

----------.Kupu Whakataki

1,1,3■ trichloroacetone he takawaenga nui i roto i te hanga o te waikawa folic.I tenei wa,1,1,3.acetone trichloropacetone, roa te huringa whakaputa(48 haora),he iti te whiriwhiringa,he iti te hua,1,1,3- Ko te ihirangi trichloropacetone he 17% anake, i muri i te tangohanga wai, ko ona ihirangi he 51.9% anake. He nui te utu whakaputa, he iti te whakatikatika hua. Ko enei katoa ka arahi ki te utu nui o te hanga waikawa folic whare, he uaua ki te whakapai ake i te ihirangi me etahi atu raruraru.Ka panui te kaituhi i te maha o nga tuhinga o roto, o tawahi hoki.I muri i te maha o nga whakamatautau me nga rangahau, ka taapirihia e matou te whakakorikori me te whakahaere i te tere o te maota, ka whakaiti i te wa tauhohenga ki te 1,1,3-3 trichloropacetone i roto i nga haora 24, me te 1,1,3-3 trichloropacetone crystallization me te purenga nui atu i te 99% me te neke atu i te 45%.

1. Nga hikoinga whakamatautau

I roto i te ipu wha-kaki me te 500ml condenser porowhita, he nui te acetone me te whakakorikori i whakakorikorihia, ka whangaia ki te maota i te pāmahana tauhohenga o te 10~30 W. Tīmatahia te wa, mutu te haere ma te maota i etahi haora i muri i te tauhohenga, ka haere tonu. te whakaoho mo te 1 haora. He whakarewa motuhake ano he rauemi i tapirihia ki te ranunga hua, ka whakaohohia mo te 1 haora i te whakamatao ki te 10 ° C crystallization, te tango i te 1,1,3-trichloroacetone.

1. 1,1,3. Te whakatau whiriwhiri o te purea trichloroacetone

Varin 3700 hau chromatograph, QF・1 tīwae whakakī me te pūtiro FID i whakamahia ki te whiriwhiri i te hua parakore o te hua me te otinga pūhaumāota.

1. Nga hua o te korerorero
2. Ko te awe o te whakakorikori i runga i te whiriwhiringa hauhauota i whakaatu i te whiriwhiringa o te acetone chlorination

Te awe nui, ka whakarārangihia e te Ripanga 1 te huinga o nga hua whakamatautau.

　　he pai rawa atu te whakakōkī amine pūhui, tae atu ki te 57.5%o. Nga tikanga whakamātautau: Innl acetone, 3nr) l māota, whakakōkī 0.6g, te pāmahana 1030°C,

1. Te awenga o te tere-maota ki te tauhohenga

I kitea e te whakamatautau he ngoikore te whiriwhiringa o nga hua o te chlorine, he pai ake te whiriwhiringa me te hua.
