He mea ʻawaʻawa loa ka waiʻona propargyl?He aha ka manaʻo hoʻomohala o ka ʻoihana propargyl alcohol?ʻO ka waiʻona Propargyl, i kapa ʻia ʻo 2-propargyl-1-alcohol, 3-hydroxymethyl acetylene a me ka ethynyl methanol, me ka molecular formula C3H4O a me ke kaumaha molekala o 56.07.He wai aniani ʻaʻohe waihoʻoluʻu me ke ʻala o nā lau ʻala.He mea maʻalahi ke huli melemele ma hope o ka mālama ʻana i ka wā lōʻihi, ʻoi aku ka maikaʻi ke ʻike ʻia i ka mālamalama.He wai wela ia, hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona a me ka etera.Hiki ke hoʻohana ʻia e like me ka rust remover, chemical intermediate, corrosion inhibitor, solvent, stabilizer, etc.
ʻO ke kūlana hoʻomohala a me ka nānā ʻana o ka ʻoihana propargyl alcohol ma Kina
ʻO ka waiʻona Propargyl he mea waiwai nui kemika, i hoʻohana nui ʻia i ka lāʻau lapaʻau, ʻoihana kemika, electroplating, pesticides, kila a me ka aila hoʻohana, etc.
Ma Kina, hoʻohana nui ʻia ka propargyl alcohol e synthesize pharmaceutical raw material fosfomycin sodium, fosfomycin calcium, SULFAPYRIDINE a me ka pesticide chlorhexidine, e helu ana ma kahi o 60% o ka huina;Ma kahi o 17% o ka wikiwiki o ka nickel leveling agents a me nā mea hoʻonani e hoʻohanaʻia no ka electroplating (ʻo ka mea hoʻolālā lōʻihi lōʻihi a me ka'ōlinolino he 1,4-butynediol, akā ua nāwaliwali ka'ōlinolino);ʻO ka hoʻohana ʻana i ka aila ma kahi o 10%;ʻO ka ʻoihana metallurgical ma kahi o 8%;ʻO nā ʻoihana ʻē aʻe e pili ana i ka 5%.
I ka makahiki 2019, he 5088.9 tons ka noi o Kina no ka waiʻona propargyl, me ka piʻi ʻana o ka makahiki he 7.3%;I ka makahiki 2020, he 5353.5 tons ka noi o Kina no ka waiʻona propargyl, me ka piʻi ʻana o ka makahiki he 5.2%;I ka makahiki 2021, ʻo ka noi no ka propargyl alcohol ma Kina he 5717.8 tons, me ka piʻi ʻana o ka makahiki he 6.8%.
ʻO BASF ka mea hana nui o ka waiʻona propargyl ma nā ʻāina ʻē, a ʻo nā mea hana nui o ka home me Shandong dongʻa fengle chemical, Henan Haiyuan fine chemical, Henan ikehu a me ka hui kemika Hebi Coal Chemical, etc. I kēia manawa, 1,4 nui Loaʻa i nā ʻoihana hana hana ʻo butanediol kekahi mau kumu kūʻai inā hoʻohana lākou i ke ala haʻahaʻa haʻahaʻa alkynaldehyde by-product recovery no ka hana ʻana i ka waiʻona propargyl.
