Doro repropargyl rine muchetura zvakanyanya here?Ndeipi tarisiro yekusimudzira yeindasitiri yedoro yepropargyl?Propargyl doro, inonzi 2-propargyl-1-doro, 3-hydroxymethyl acetylene uye ethynyl methanol, ine molecular formula C3H4O uye molecular uremu hwe56.07.Imvura inopenya isina ruvara ine kunhuhwirira kwemashizha anonhuhwirira.Zviri nyore kushanduka yero mushure mekuchengetedza kwenguva refu, kunyanya kana yaiswa pachiedza.Imvura inopfuta, inonyungudika nyore mumvura, doro uye ether.Inogona kushandiswa se ngura inobvisa, kemikari yepakati, corrosion inhibitor, solvent, stabilizer, nezvimwe.
Mamiriro ebudiriro uye Tarisiro Ongororo yepropargyl doro indasitiri muChina
Propargyl doro chinhu chakakosha chemakemikari raw material, iyo inoshandiswa zvakanyanya muminda yemishonga, indasitiri yemakemikari, electroplating, mishonga yekuuraya zvipembenene, kushandiswa kwesimbi nemafuta, nezvimwewo nehuwandu hwakawedzerwa, inowanzogadzirirwa nekuita kwe formaldehyde uye acetylene.
MuChina, propargyl doro rinonyanya kushandiswa kugadzira mishonga mbishi zvinhu fosfomycin sodium, fosfomycin calcium, SULFAPYRIDINE uye mushonga wezvipembenene chlorhexidine, inoverengera inenge 60% yehuwandu;Inenge 17% yekutsanya nickel leveling agents uye zvinopenya zvinoshandiswa pa electroplating (iyo yakareba-inobata mumiririri uye inopenya ndeye 1,4-butynediol, asi kupenya hakuna simba);Kushandiswa kwemafuta kunotora chikamu che10%;Metallurgical industry accounts about 8%;Mamwe maindasitiri anoita 5%.
Muna 2019, kudiwa kweChina kwepropargyl doro kwaive 5088.9 matani, nekuwedzera kwegore negore kwe7.3%;Muna 2020, kudiwa kweChina kwepropargyl doro kwaive 5353.5 matani, nekuwedzera kwegore negore kwe5.2%;Muna 2021, kudiwa kwepropargyl doro muChina kwaive 5717.8 matani, nekuwedzera kwegore negore kwe6.8%.
BASF ndiyo inonyanya kugadzira doro repropargyl kune dzimwe nyika, uye vagadziri vakuru vepamba vanosanganisira Shandong dong'a fengle chemikemikari, Henan Haiyuan yakanaka makemikari, Henan simba uye kemikari boka Hebi Coal Chemical, nezvimwewo. -butanediol mabhizinesi ekugadzira ane zvimwe zvakanakira mutengo kana vakashandisa yakaderera-kudzvanywa alkynaldehyde ne-chigadzirwa kudzoreredza nzira yekugadzira propargyl doro.
