Kulimbikitsa kasamalidwe kabwino ndikuwongolera mtundu wazinthu za mowa wa propargyl ndi 1,4 butynediol

Mu Epulo, 2019, mankhwala a Haiyuan adakhazikitsa njira yopulumutsira mphamvu yopulumutsa mphamvu pakuwongolera pampu ya mowa wa propargyl mozungulira kutumizidwa konse kwa kampaniyo ndi cholinga cholimbitsa kasamalidwe ka mankhwala abwino komanso poyambira pakuwongolera bwino kwazinthu komanso kuchepetsa kugwiritsa ntchito.

Ukadaulo wopulumutsa mphamvu wa propargyl mowa wogawa kutentha mpope distillation umakongoletsedwa ndi Tianjin University Kutengera zida zogwirira ntchito zomwe zilipo ndikugwiritsa ntchito mawerengedwe a pulogalamu yamapulogalamu.Ukadaulo wa distillation wa diaphragm ndi ukadaulo wa kupopera kutentha kwapampu zimaphatikizidwa kwa nthawi yoyamba, ndipo ukadaulo uwu umagwiritsidwa ntchito pakuphatikiza mowa wa propargyl ndi 1,4 butynediol kwa nthawi yoyamba.Mphamvu yamagetsi imagwiritsidwa ntchito m'malo mwa nthunzi, kotero kuti mphamvu yogwiritsira ntchito mphamvu yofunikira pakukhazikika kwa mowa wa propargyl ndi butynediol ikhoza kuchepetsedwa ndi 25% poyerekeza ndi ndondomeko yachizolowezi, ndipo mtengo wapachaka ukhoza kupulumutsidwa ndi 20million yuan.

The diaphragm distillation luso ndi kuwonjezera ofukula diaphragm pakati pa ochiritsira distillation ndime, ndi kugawa gawo lapakati la ochiritsira distillation ndime mu magawo awiri: chakudya mbali ndi kuchira mbali.Pogwiritsira ntchito, pakulekanitsa zigawo zitatu, zigawo zoyera zimatha kupezeka pamwamba, pakati ndi pansi pa nsanja motsatira, kuti muzindikire kulekanitsa zigawo zitatu mu nsanja imodzi.Mfundo yopulumutsira mphamvu yaukadaulo wa diaphragm distillation ndikuphatikiza kulekanitsa kusanachitike kwa zigawo ndi distillation, kuchepetsa kusakanizikana kwa zinthu ndi zovuta zolekanitsa, kuti achepetse ndalama zoyambira ndikuchepetsa mtengo wogwirira ntchito.Ukadaulo wa distillation wa diaphragm ndiwoyenera makamaka kuti dongosololi lilekanitsidwe momwe zigawo zapakati zowira zimawerengera zambiri ndipo zigawo zowala ndi zigawo zolemetsa zimawerengera gawo laling'ono, ndikupulumutsa pafupifupi 30% ya ndalama zoyambira.Zopangira zopangira mowa wa propargyl ndi mowa wa propargyl 3.2%, madzi 90,8%, ndi butynediol 6%.Madzi, monga gawo lapakati, amawerengera ambiri, omwe amakwaniritsa zofunikira zaukadaulo wa diaphragm distillation.

Zaka 3-5 zikubwerazi, Henan Haiyuan Fine Chemical Co., Ltd. yadzipereka kukhala chizindikiro chamakampani opanga mankhwala ku China, ndipo imayesetsa kuyendetsa makampani kuti atenge zobiriwira, zopulumutsa mphamvu, zapamwamba komanso zapamwamba. tech njira kudzera mu chitukuko chake.
