I tetahi taha, ka whakaratohia e te hangahanga he tikanga purenga o te 1,1, 3-trichloroacetone, kei roto i te tikanga nga waahanga e whai ake nei
Kohiko:
(1) Maharahara 1,1, 3-trichloroacetone i konatunatua ki te wai;
(2) Recrystallization o te otinga o runga i muri i te tu;Waihoki
(3) ka tātarihia nga tioata totoka rerystallized ka horoi ki te wai;
Na, i te Hipanga (1), ko te tauwehenga o te taumaha o te 1,1, 3-trichloroacetone ki te nui o te wai he 1
0.1-2).
He pai ake, i te Hipanga (1), ko te tauwehenga o te taumaha o te 1,1, 3-trichloroacetone hua masivesivá ki te nui o te wai ka taea te 1:
(0.4-0.6), he mea pai ake hei 1:0.5;I roto i te tenenga, te inenga o 1,1, 3-trichloroacetone hua masivesivá me te wai te whakahaere i roto i runga ake.
Ko te awhe o te parakore teitei 1,1, 3-trichloroacetone ka taea te whiwhi.
E ai ki te hanga o naianei, i te taahiraa (1), ka taea te whakarite i te 1,1, 3-trichloroacetone hua masivesivá me te wai i te mahana o te 10-50 ℃
Whakaranuhia mo te 10-30 meneti i raro i nga tikanga, ka waiho mo te 10-30 meneti;He pai ake, i te Hipanga (1), i kii te 1,1, 3-trichloropropyl
I konatunatuahia te ketone ki te wai i te mahana o te 30-35 ℃ mo te 25-30 meneti, ka tu mo te 10-15 meneti;I roto i te tenenga o naianei
, te whakamahi i te 1,1, 3-trichloroacetone masivesivá hei rauemi mata, i roto i te hohenga tauhohenga, i konatunatua ki te wai, i whakakorikoria ki tetahi pāmahana i muri i te tu.
Te whakamaarama.I muri i te whakamaaramatanga, ka tangohia te paparanga hinu o raro, ko te nuinga ma te tango i nga poke o te maota teitei me te waiho i te otinga o runga hei whakamahi i muri mai.
E ai ki te tenenga, i te taahiraa (1), ka konatunatua te 1,1, 3-trichloroacetone ki te wai, ka taea hoki te whakakorikori.
Nga tikanga, karekau he herenga motuhake mo nga ahuatanga whakaohooho me nga taputapu, mena ka taea e te 1,1, 3-trichloroacetone te marumaru.
Ka taea te whakakotahi i te hua ki te wai.He pai ake, ko te 100-300r / min te reiti whakauru.
I roto i te tenenga o naianei, he pai ake te wai kua whakakorehia te wai.
E ai ki te tenenga, i roto i te taahiraa (2), ko nga tikanga rerystallization pea: te mahana mai i te 0 ki te 35 ℃, te wa mai i te 0.5 -
10 haora, he pai ake, ka mahia te rerystallization i te tere whakaoho o 50-300 RPM;He pai ake, ko te reknot
Ka tapirihia ano te wai i roto i te tukanga whakatioatanga, ka whakauruhia te wai i te tere o te 200-600 ml / min;I raro i enei tikanga, rerystallization tōtika
He pai nga hua.
[0034] I tua atu i te pai rawa atu, ko nga tikanga rerystallization ko: te mahana o te 10-15 ℃, te wa o te 2-3 haora, me nga tikanga rerystallization.
Ka whakaohohia te karaihe i te tere o te 100-200 RPM ka whakauruhia te wai i te tere o te 300-500 ml / min.
I raro i enei tikanga, he pai ake te painga o te whakamaarama.
I roto i te tenenga o naianei, he iti ake te whakamahana whakamaaramatanga e whakaahuatia ana i te taahiraa (2) i tera o te 1,1, 3-trichloroacetone i te taahiraa (1)
Te pāmahana i konatunatua te hua ki te wai.
E ai ki te tenenga, i te Hipanga (3), ko te ranunga tauhohenga i muri i te Hipanga (2) ka taea te tātari ma te pehanga kati, ka taea ranei
Ka whiwhi nga tioata totoka ma te pehi tika i te pereti tatari kei raro o te reactor.I roto i tenei mea hanga, he pai ake te whakamahi i te hau me te hauota/ranei
Te tātari pehanga, he pai ake te whakamahi hauota mo te tātari pehanga, a ko te pehanga ka taea te 0.1-0.2MPa, he pai ki te 0.12 -
0. 18 mpa.
E ai ki te tenenga, ka horoia te karaihe i muri i te filtration pehanga ki te wai, ka horoia taua wai.
Kaore he rohe motuhake, hei tauira, ka taea e koe te whiriwhiri i te 1-2kg o te rehu wai horoi i raro i te ahua o te pāmahana o te 2-25 ℃, me te rehu.
Karekau he rohe tere motuhake.
E ai ki te tenenga, te ma o te 1,1, 3-trichloroacetone hua masivesivá kia 50-65 % i te taimaha.
