Kumbali imodzi, kupangidwaku kumapereka njira yoyeretsera ya 1,1, 3-trichloroacetone, momwe njirayo ili ndi njira zotsatirazi.

Kung'anima:

(1) 1,1, 3-trichloroacetone wosakanizidwa ndi madzi;

(2) Recrystallization wa chapamwamba njira atayima;Komanso

(3) makhiristo olimba opangidwanso amasefedwa ndikutsukidwa ndi madzi;

Momwe, mu Gawo (1), chiŵerengero cha kulemera kwa 1,1, 3-trichloroacetone yomwe yanenedwa ku kuchuluka kwa madzi ndi 1.0.1-2).

Makamaka, mu Gawo (1), kulemera kwa 1,1, 3-trichloroacetone crude product ku kuchuluka kwa madzi kungakhale 1:

(0.4-0.6), kukonzedwanso ngati 1: 0.5;Popanga, mlingo wa 1,1, 3-trichloroacetone crude product ndi madzi umayendetsedwa pamwambapa.

Mitundu yambiri yoyera 1,1, 3-trichloroacetone imatha kupezeka.

Malinga ndi zomwe zapezedwa pano, mu sitepe (1), 1,1, 3-trichloroacetone crude product ndi madzi zitha kukonzedwa pa kutentha kwa 10-50 ℃

Sakanizani kwa mphindi 10-30 pansi pa zikhalidwe, ndiyeno muyime kwa mphindi 10-30;Makamaka, mu Gawo (1), anati 1,1, 3-trichloropropyl

Ketone yaiwisi imasakanizidwa ndi madzi pa kutentha kwa 30-35 ℃ kwa mphindi 25-30, kenako inayima kwa mphindi 10-15;M'zinthu zamakono

, pogwiritsa ntchito 1,1, 3-trichloroacetone crude monga zopangira, mu ketulo anachita, wothira madzi, wosonkhezeredwa ndi kutentha kwina atayima.

Delamination.Pambuyo pa delamination, mafuta otsika amachotsedwa, makamaka pochotsa zonyansa zambiri za chlorine ndikusiya yankho lapamwamba kuti ligwiritsidwe ntchito mtsogolo.

Malingana ndi kupangidwa, mu sitepe (1), 1,1, 3-trichloroacetone yosakanizidwa ndi madzi ndipo imathanso kugwedezeka.

Mikhalidwe, yomwe palibe malire enieni pazochitika zolimbikitsa ndi zida, bola ngati 1,1, 3-trichloroacetone ikhoza kukhala yovuta.

Mankhwalawa akhoza kusakanikirana mofanana ndi madzi.Makamaka, mlingo wosakanikirana ndi 100-300r / min.

Masiku ano, madziwo ndi madzi opangidwa ndi deionized.

Malinga ndi kupangidwa, mu sitepe (2), zinthu recrystallization akhoza kukhala: kutentha kuchokera 0 mpaka 35 ℃, nthawi kuchokera 0.5 -

Maola 10, makamaka, recrystallization ikuchitika pa mlingo wolimbikitsa wa 50-300 RPM;Makamaka, reknot

Madzi amawonjezeredwa mu ndondomeko ya crystallization, momwe madzi amawonjezeredwa pa mlingo wa 200-600 ml / min;Pazimenezi, recrystallization dzuwa

Chipatso ndi chabwino.

[0034] Kupitilira apo, mawonekedwe a recrystallization ndi: kutentha kwa 10-15 ℃, nthawi ya maola 2-3, ndi mikhalidwe yokonzanso.

Crystal imagwedezeka pa mlingo wa 100-200 RPM ndipo madzi amawonjezeredwa pa mlingo wa 300-500 ml / min.

Pazifukwa izi, recrystallization zotsatira ndi bwino.

Pakupangidwa kwamakono, kutentha kwa recrystallization komwe kufotokozedwa mu sitepe (2) ndikotsika kuposa kwa 1,1, 3-trichloroacetone mu sitepe (1)

Kutentha komwe mankhwalawa amasakanikirana ndi madzi.

Malinga ndi kupangidwa, mu Gawo (3), zomwe zimasakanikirana pambuyo pa Gawo (2) zitha kusefedwa ndi kutsekeka kotseka, kapena kutha

Makhiristo olimba amapezedwa mwa kukanikiza mwachindunji mu mbale ya sieve pansi pa riyakitala.Pazopanga zamakono, mpweya ndi/kapena nayitrogeni zimagwiritsidwa ntchito bwino

Pressure kusefera, ndi bwino kugwiritsa ntchito nayitrogeni kwa kuthamanga kusefera, ndipo kuthamanga kungakhale 0.1-0.2MPa, makamaka 0,12 -

0.18 mpa.

Malinga ndi kupangidwako, kristalo wokhazikika pambuyo pa kusefera kwamphamvu imatsukidwa ndi madzi, momwe madziwo amatsukidwa.

Palibe malire enieni, mwachitsanzo, mutha kusankha 1-2kg yotsuka madzi opopera pansi pa kutentha kwa 2-25 ℃, ndi kupopera mbewu mankhwalawa.

Palibe malire enieni othamanga.

Malinga ndi kupangidwako, chiyero cha 1,1, 3-trichloroacetone chosakanizidwa chikhoza kukhala 50-65 % kulemera kwake.

Kupangidwa kwamakono, kumbali ina, kumaperekanso folic acid yomwe imakonzedwa ndi njira iliyonse yomwe tafotokozayi

Njira yamadzimadzi ya 1,1, 3-trichloroacetone imagwiritsidwa ntchito mwachindunji kukonza folic acid.

Kugwiritsa ntchito njira yoyeretsera zomwe zidapangidwa, monga stratified m'zigawo, kusefera kwa crystallization ndi zina zotero, zitha kuchitika munjira yotsekedwa.

Environment-wochezeka, ndi kuchepetsa kwambiri m'badwo wa madzi zinyalala, palibe zinyalala organic solvents ndi organic zinyalala mpweya;Komanso, kuyeretsa njira

Palibe zosungunulira za organic zomwe zimayambitsidwa, ndipo zonyansa zambiri za chlorine zimachotsedwa panthawi yoyeretsa, kotero palibe chiwopsezo chamtundu wa folic acid.

Njirayi imagwiritsa ntchito madzi ngati chosungunulira cha crystallization, ndipo njira yoyeretsera yamadzimadzi ya 1,1, 3-trichloroacetone imagwiritsidwa ntchito mwachindunji kupanga folic acid.

Zokolola zonse za kupatsidwa folic acid zitha kuonjezeredwa ndi 5 % polemera, ndipo chiyero chimaposa 99.2% polemera, chomwe chingapezeke chapamwamba kwambiri.
