Hana kūikawā i ka hana ʻana i ka waiʻona propargyl, 1,4 butynediol a me 3-chloropropyne
ʻO ke kaʻina hana hana ʻona Propargyl a me ka nānā ʻana i ka mākeke
Nā waiwai a me ka hoʻohana ʻana o 2 propargyl alcohol
2.1 Hana maikaʻi ma luna a me ka hoʻopuehu
Propargyl waiʻona i ikaika polarity a me ka hydrophilicity, no ka mea, he -OH, a me ka hydrophobicity no ka mea i loko o ka hydrocarbon pūʻulu, no ka mea, keia mau waiwai hana propargyl waiʻona e like me ka non-ionic surfactant, e hōʻike ana i ka maikaʻi hana, me ka maikaʻi haʻahaʻa foaming, defoaming a me ka wettability.ʻO ka hapa nui o nā mea pulu pulu maʻalahi, ʻoiai ʻo ka hapa nui o nā mea hoʻoheheʻe kemika he maikaʻi ʻole ka pulu.Hoʻohālikelike ʻia me nā surfactants ʻē aʻe, he liʻiliʻi ke kaumaha molekala nā alkyl alcohols, maʻalahi ka hoʻopuehu ʻana, maikaʻi ka hoʻopuehu ʻana, maikaʻi ka pulu a me ka haʻahaʻa haʻahaʻa.Ma kekahi ʻaoʻao, loaʻa nā pūʻulu kaulahao kumu hydrocarbon, ʻo ka hapa nui o nā hui liʻiliʻi (maʻamau ʻo methyl), ʻelua mau pūʻulu polar i loko o ka hale.Ma muli o kēia ʻano kemika, hiki i nā alkyl alcohols ka pulu maikaʻi.Ma ka ʻaoʻao ʻē aʻe, hiki i nā kaulahao alkyl-branched i loko o ka waiʻona propargyl ke hōʻemi i ka huki ʻana ma waena o nā molekele e pili ana a hana i kahi kiʻiʻoniʻoni hoʻonui a hiki ke hanu i ka palena kinoea-wai.No laila, ʻaʻole ia wale nō ka hana ʻana i ka foam ponoʻī, akā loaʻa nō hoʻi i kekahi mau defoaming hiki, a hiki ke hui pū ʻia me nā mea hana defoaming ʻē aʻe e pāʻani i kahi ʻoi aku ka nui.
2.2 ʻOi loa metala corrosion inhibition
I kēia manawa, ʻo nā mea hoʻopaʻapaʻa metala i hoʻohana ʻia i ka media acidic ka hapa nui o nā pūhui organik, nona ka mana adsorption ikaika ma nā ʻili metala.ʻO ka molecular structure o ka propargyl alcohol e pili ana i nā hui polar a me nā hui non-polar.He adsorbent ia o nā mea hoʻopiʻi corrosion organik.Ma ka ʻaoʻao hoʻokahi, ʻo nā paʻa hoʻohui i hoʻokumu ʻia ma waena o ka propargyl alcohol a me nā mea metala e hāpai i ka adsorption o ka waiʻona i kekahi ʻano.I ka manawa like, hoʻonāwaliwali ʻia ka pilina PI i loko o ka propargyl alcohol mole, hoʻāla ʻia ka paʻa triple, a kokoke ka hui hydroxyl polar i ka paʻa acetylene, e hoʻonui ai i ka adsorption.Ma ke ʻano alkaline, hiki i ka waiʻona proparynyl ke hoʻopili iā Langmuir ma luna o ka alumini maʻemaʻe, he hopena maikaʻi ka pale ʻana i ka corrosion.ʻO ka waiʻona Propargyl ma muli o kāna hana maikaʻi loa, he ākea ākea o ka hoʻohana ʻana, hoʻohana nui ʻia i nā intermediates pharmaceutical, copper a nickel plating polish, pesticide intermediate.Eia kekahi, hiki ke hoʻohana ʻia ka waiʻona propargyl ma ke ʻano he mea hoʻopaʻa corrosion o ka wela kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe a me ka waika hydrochloric kiʻekiʻe i loko o ka aila a me ke kinoea maoli Wells.
2.3 Hoʻohana i ka waiʻona propargyl
① ʻO nā mea koʻikoʻi koʻikoʻi i ka synthesis organik: i ka ʻoihana lāʻau lapaʻau, ʻo proparynol kahi mea koʻikoʻi waena o ka sodium fosfomycin, calcium fosfomycin, sulfadiazine, a hoʻohana pū ʻia i ka hana ʻana i ka allyl alcohol, acrylic, vitamin A a me nā huahana lāʻau ʻē aʻe;② Electroplating ʻoihana hoʻomālamalama: propargyl alcohol compounds he maikaʻi ke kūlike a me ka glossiness, a me ka pale māmā maikaʻi i ka nickel plating.He mea maʻamau ka hā o ka nickel plating brightener, hoʻohana nui ʻia i ka ʻoihana electroplating;③ Mea hoʻoneʻe ʻeleʻele koʻikoʻi: hiki i ka proparynyl alcohol a me kona mau mea hoʻohui i lalo ke pale i ka pala o ka hao, keleawe, nickel a me nā metala ʻē aʻe e nā mea waikawa e like me ka acetic acid, phosphoric acid, sulfuric acid, hydrochloric acid;(4) ʻO ka hoʻomohala ʻana i ka ʻaila: ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe a me ka kiʻekiʻe o ka hydrochloric acid corrosion inhibitors ʻo ia nā mea nui o nā mea hoʻopiʻi ʻawaʻawa maikaʻi loa i ka ʻaila a me ke kinoea Wells;⑤ hiki ke hoʻohana ʻia e like me ka solvent, chlorinated hydrocarbon stabilizer, fungicide a me nā mea maka.
Kaʻina hana hana
I kēia manawa, ʻo ke ʻano hoʻomākaukau nui loa o ka propargyl alcohol ma ka home a ma waho o ka hopena o ka formaldehyde a me ka acetylene e hana ai i ka waiʻona propargyl a me ka butynediol, ʻo ia ka propargyl alcohol he hopena o ka butynediol.Ma ka hoʻoponopono ʻana i ka nui o ka intake o ke kinoea acetylene, hoʻomaikaʻi i ke kaomi ʻana, hoʻoholo i ka waiwai pH maikaʻi loa, hiki i ka lakio o ka waiʻona propargyl a me ka butynediol ke hiki i 1:1.6, i mea e hoʻomaikaʻi ai i ka koho o ka waiʻona propargyl.Kaʻina Hana: E hoʻohui i ka copper oxygenated catalyst i loko o ka pahu hoʻāla, e hoʻohui i ka wai palupalu, e hoʻoulu no kahi 20min, a ninini i ka hui ʻana o ka catalyst a me ka wai i loko o ka pahu hoʻoulu me ka pamu.Hoʻohui ʻia ka wai palupalu a me ka formaldehyde i ka pahu i hoʻoulu ʻia e hoʻomākaukau i ka hopena hoʻoulu ʻia me 6% ~ 10% formaldehyde.Hoʻokomo ʻia ka wai hoʻoulu ʻia i loko o ka reactor me ka plunger feed pump e like me ke ana ʻana o ka kahe kahe, a ua hoʻomaka ka compressor acetylene e hoʻoponopono i ka kahe o ka acetylene a hoʻomalu i ka wikiwiki o ka hopena.Ua hoʻomaka ka ʻōnaehana wela a me ke kaomi o ka reactor e hoʻomalu i ka mahana o ka reactor ma 90 ~ 130 ℃ a me ke kaomi ma (2.0 ± 0.1) MPa.Holo ka ʻōnaehana hopena ma hope o ka hoʻokuʻu ʻana, a hoʻi ka hoʻokuʻu i ka pahu i hoʻoulu ʻia.Ua ʻike ʻia ka ʻike o ka formaldehyde ma hope o 0.5h.I ka emi ʻana o ke koena formaldehyde ma mua o 0.3%, ua hoʻopau ʻia ka pōʻaiapuni a ua hoʻoheheʻe ʻia ka hopena hopena i loko o kahi pahu waena me ka propargyl a me ka butanediol ma kahi o 4% a me 6%, kēlā me kēia.Pono e hoʻololi pinepine ʻia ka catalyst i ke kaʻina hana, a ʻo ka manawa hoʻololi he 30 a 40 mau lā.Hoʻohana ʻia ʻo Nitrogen me kahi catalyst e wehe i nā mea mai ka ʻōnaehana i ka wā e pani ai.Ma hope o ka hoʻokaʻawale ʻana me ka kānana kaomi, waiho ʻia ke koena catalyst i loko o ka pahu mālama catalyst i hoʻopau ʻia a hoʻopaʻa ʻia me ka wai.Ua kākau hou ʻia ka catalyst hou i ka pōʻai hou o ka ʻōnaehana batching.
Ka nānā 'ana i ka mākeke wai'ona Propargyl
ʻO Dezhou Tianyu Chemical Co., Ltd. kekahi o nā hana liʻiliʻi o ka waiʻona propargyl a me nā ʻoihana nui butanediol, ka puka makahiki o ka propargyl alcohol 1200T, butanediol 2400T, a me ka maikaʻi o Germany BASF like.Henan Haiyuan Fine Chemical Co., Ltd. i hoʻonui a hoʻonui i ka papahana ma ke kumu o ke kaʻina hana mua o Shandong Dongfang Le, me ka puka makahiki o 1200T propionyl alcohol a me 2400T butanediol.Ma Kina, hoʻohana nui ʻia ka waiʻona proparynyl i ka synthesis o nā lāʻau lapaʻau, sodium phosphate, calcium phosphate, sulfonamide a me nā pesticides, e helu ana ma kahi o 60% o ka huina.ʻO ka nickel plating wikiwiki a me ka hoʻopili uila he 17%.ʻO ka hanaʻaila ma kahi o 10%;ʻO ka hapa o ke kila ma kahi o 8 pākēneka;ʻO nā ʻoihana ʻē aʻe e pili ana i ka 5%.ʻO ka waiʻona Propargyl kahi mea ʻawaʻawa loa e pili ana i ka hana, kūʻai aku a me ka hoʻohana.ʻO ia ka lāʻau lapaʻau i lalo, pesticide, metallurgical media a me nā ʻano mea kōkua ʻē aʻe a i ʻole kekahi o nā ʻāpana.I ka hopena o ka makahiki 2017, ʻo 4,770T /a ka nui o ka hana ʻana o ka home, a ʻo ka noi ma kahi o 4,948T / a.Kaulike ka lako a me ke koi, me ka nele i kekahi manawa.
Hoʻopau
I kēia manawa, ʻoi aku ka ikaika o ka mākeke propanol kūloko, ʻo kāna kahua noi nui loa ʻo ia ka ʻoihana lāʻau lapaʻau fosfomycin moʻo huahana, e ka mākaʻikaʻi hoʻomāinoino antibiotic a me ka hoʻoikaika ʻana i ka ʻoihana electroplating, nā mea hoʻohana propanol downstream i ka wā pōkole ʻaʻole i hoʻonui ʻia.I kēia manawa, ke hoʻāʻo nei mākou e hoʻomaikaʻi hou i ke kaʻina hana hou, hoʻomaikaʻi mau i ka hua o ka waiʻona propargyl, a hoʻoikaika e hōʻemi i ka hoʻohana ʻana i ka ikehu o nā huahana propargyl alcohol.ʻO ka hoʻokō ʻana i kēia mau hana e hoʻemi hou i ke kumukūʻai o nā huahana propargyl alcohol, hoʻomaikaʻi i ka hoʻokūkū o nā huahana, a hoʻoikaika e hoʻokō i ka noi kūloko a me nā ʻāina ʻē no ka propargyl waiʻona a me nā moʻo o nā huahana, e hana i nā pono waiwai a me ka pilikanaka.
