N,N-Dimethylacetamide CAS: 127-19-5
Hunhu hwemakemikari: Hunhu hwemakemikari hwakafanana zvikuru neN,N-dimethylformamide, uye imusanganiswa weamide. Kana pasina acid kana alkali, haiori kana yapiswa kusvika yafashaira pasi pekumanikidzwa kwakajairika, saka inogona kunyungudutswa pasi pekumanikidzwa kwakajairika. Mwero wehydrolysis unononoka zvikuru. Kana N,N-dimethylacetamide ine 5% yemvura ikapiswa pa95°C kwemaawa 140, 0.02% chete ndiyo inonyungudutswa. Zvisinei, kana paine acid nealkali, mwero wehydrolysis unowedzera. Saponification inoitika kana yapiswa pamberi pealkali yakasimba.
Imvura inoonekera zvakanaka uye ine hunyanzvi hwepamusoro.
Munda wekushandisa
1. Dimethylacetamide yemishonga inoshandiswa mumishonga inokosha uye inoshandiswa zvakanyanya mukugadzira amoxicillin, cephalosporins nemimwe mishonga. Semushonga unonyungudutsa kana kuti cocatalyst, dimethylacetamide inogona kuvandudza mhando yezvigadzirwa uye goho zvichienzaniswa nezvinwiwa zvechinyakare zveorganic. Muna 2000, kudiwa kwedimethylacetamide muindasitiri yemishonga kwaive anenge 6kt. Kudiwa kwedimethylacetamide muna 2006 kwaive anenge 9.6kt. 2. Kugadzirwa kweAcrylic fiber Mukugadzirwa kweacrylic fiber, vamwe vanoshandisa nzira yedimethylacetamide. Parizvino, kugadzirwa kweacrylic fiber yemumba Chemicalbook inonyanya kusanganisira sodium thiocyanate nzira mbiri-nhanho, dimethylformamide nzira imwe-nhanho uye dimethylacetamide nzira yeorganic wet zvichienderana nezvinwiwa. Kubva pamaonero emaitiro nemidziyo, kushandiswa kwezvinhu, kukanganisa kwezvakatipoteredza, mhando yezvigadzirwa, Zvinhu zvakawanda zvakaita sekushanda kwemashure ekugadzirisa, mwero wenzvimbo uye mafambiro ekusimudzira ekunze zvakawedzera kutsvagisa kwekushandisa uye kuedza kusimudzira. Dimethylacetamide yakashandiswa sekuenzanisa kwakazara. Nzira yeSodium thiocyanate ine matanho maviri uye nzira ye dimethylacetamide organic wet yakashandiswa. Iyi ndiyo nzira inovimbisa zvikuru. Parizvino, nzvimbo dzakawanda dze acrylic fiber muChina dzinoshandisa nzira dzemvura dzichishandisa dimethylacetamide semushonga unonyungudutsa.

Ruzivo rweKambani
MIT-IVY INDUSTRY CO., LTD inogadzira uye inotumira kunze madhayi emakemikari akanaka uye mishonga yemishonga muChina.
Vanonyanya kugadzira zvigadzirwa zveaniline series uye zvigadzirwa zvechlorine series.
MIT –IVY Chemicals Industry Co.,Ltd. ikambani inotungamira mukugadzira makemikari kwemakore makumi maviri nerimwe ine michina yekugadzira yakakwana uye manejimendi nekuchengetedza michina zvine hungwaru.
Tinoshandisa tekinoroji yepamusoro yekugadzira uye nzira dzekuyedza kuti tiwane kugadzirwa, kudzora mhando kuti zvisvike padanho repamusoro. Takatenderwa neSGS, ISO9001, ISO140 01, GB/HS16949 uye T28001.
Zvigadzirwa zvikuru zveMit-Ivy zvinosanganisira zvinotevera:
API, mishonga yepakati, dhayi yepakati, makemikari akakosha, pendi yemumaindasitiri inoburitswa nemvura uye zvinhu zvitsva zvine simba.
Misika yedu mikuru inosanganisira America, India, Africa, Indonesia, Turkey, South-east Asia, West Asia nezvimwewo. MIT-IVY Industry Main products ine 97% yemusika wemuno unonyanya kugadzira nekutarisira, Tinogona kupa zvigadzirwa nemutengo unokwikwidzana. Nemhando yepamusoro uye mutengo uye tinokugamuchirai kuti mubvunze. Kambani yedu ine vanhu vane hunyanzvi vanodzidza nezve chemical R&D uye manejimendi, vanopa zvigadzirwa zvemakemikari zvakanaka zvine mhando yepamusoro uye sevhisi yepedyo, vanopawo zvigadzirwa zvakagadzirwa zvinoenderana nezvinodiwa nevatengi vedu. Tine timu yekutarisira yakanaka uye inozvikurudzira ine pfungwa yakafanana, ine hanya uye yakazvipira kuburikidza nekushanda pamwe chete, timu yedu inoedza kubudirira mukufadza vatengi vedu nesu. Tinogara tichigadzira zvigadzirwa zvedu uye tichivandudza network yedu yekutengesa. Saka, tinotanga nzira yekutanga yekutengesa pa internet muChina, inova kutengeserana kwezvitoro zvemapakeji madiki kuunza nzira dzakasiyana siyana dzekutarisira. Zvigadzirwa zvedu zvinotumirwa kune dzimwe nyika kuSouth Korea, Vietnam, Australia, Europe neSouth America, zvinokurudzirwa zvikuru nevatengi vedu. Tinosimbirira pakutenda kwemanejimendi "Musika ndiyo kambasi yedu, Hunhu hupenyu hwedu, Chikwereti mweya wedu". Kuvimba kwevatengi ndiko kwatinotungamira, kugutsikana kwavo ndicho chinangwa chedu chinotinetsa.
Basa reVatengi reBrand:
