Okhazikika pakupanga mowa wa propargyl, 1,4 butynediol ndi 3-chloropropyne
Njira yopanga mowa wa Propargyl ndi kusanthula msika
Katundu ndi ntchito 2 propargyl mowa
2.1 Kuchita bwino kwambiri pamtunda komanso kubalalitsidwa
Propargyl mowa ali amphamvu polarity ndi hydrophilicity, chifukwa lili -OH, ndi hydrophobicity ndi chifukwa lili hydrocarbon gulu, chifukwa katundu kupanga propargyl mowa monga sanali ionic surfactant, kusonyeza ntchito kwambiri, ndi zabwino otsika thobvu, defoaming ndi wettability.Zinthu zambiri zonyowetsa zimatuwira mosavuta, pamene mankhwala ambiri ochotsa thobvu sanyoweratu bwino.Poyerekeza ndi ma surfactants ena, ma alkyl alcohols ali ndi kulemera kochepa kwa maselo, kufalikira kosavuta, kubalalitsidwa kwabwino, kunyowa kwabwino komanso thovu lochepa.Kumbali imodzi, ma alkyl alcohols amakhala ndi magulu a hydrocarbon base branched chain, makamaka magulu ang'onoang'ono (makamaka methyl), pali magulu awiri a polar pamapangidwe.Chifukwa cha kapangidwe ka mankhwalawa, ma alkyl alcohols amakhala ndi madzi abwino.Kumbali ina, maunyolo a alkyl-branched mu propargyl mowa amatha kuchepetsa kukopa pakati pa mamolekyu oyandikana nawo ndikupanga filimu yowonjezera yowonjezereka komanso yopumira pamalire amadzi a gasi.Choncho, sizimangopanga thovu lokha, komanso zimakhala ndi mphamvu zina zowononga, ndipo zimatha kusakanikirana ndi zina zowonongeka kuti zigwire ntchito yaikulu.
2.2 Kuletsa kwachitsulo kwabwino kwambiri
Pakadali pano, ma metal corrosion inhibitors omwe amagwiritsidwa ntchito mu acidic media nthawi zambiri amakhala ma organic compounds, omwe ali ndi mphamvu zotsatsa pazitsulo.Mapangidwe a maselo a mowa wa propargyl amaphatikizapo magulu a polar ndi magulu omwe si a polar.Ndi adsorbent ya organic corrosion inhibitors.Kumbali imodzi, mgwirizano womwe umapangidwa pakati pa mowa wa propargyl ndi ma atomu achitsulo amalimbikitsa kulowetsedwa kwa mowa pamlingo wina.Panthawi imodzimodziyo, mgwirizano wa PI mu molekyulu ya mowa wa propargyl umafooka, mgwirizano wapatatu umatsegulidwa, ndipo gulu la polar hydroxyl liri pafupi ndi mgwirizano wa acetylene, womwe umapangitsa kuti adsorption.Mu alkaline sing'anga, mowa wa proparynyl ukhoza kukopa Langmuir pa aluminiyamu yoyera, yomwe imakhala ndi zoletsa zabwino zoletsa dzimbiri.Mowa wa Propargyl ndi chifukwa cha ntchito yake yabwino kwambiri, uli ndi ntchito zambiri, zomwe zimagwiritsidwa ntchito makamaka pakati pa mankhwala, mkuwa kapena nickel plating polish, mankhwala ophera tizilombo.Kuphatikiza apo, mowa wa propargyl ukhoza kugwiritsidwanso ntchito ngati choletsa kutentha kwambiri, kuthamanga kwambiri komanso kuchuluka kwa hydrochloric acid mumafuta ndi gasi lachilengedwe.
2.3 Kugwiritsa ntchito mowa wa propargyl
① Zofunika zapakatikati pakupanga organic: m'makampani opanga mankhwala, proparynol ndi gawo lapakati la sodium fosfomycin, calcium fosfomycin, sulfadiazine, ndipo amagwiritsidwanso ntchito popanga allyl mowa, acrylic, vitamini A ndi mankhwala ena;② Makina opangira magetsi opangira magetsi: mankhwala opangira mowa wa propargyl amakhala ndi mawonekedwe abwino komanso onyezimira, komanso kukana kuwala kwa nickel plating.Ndi m'badwo wachinayi nickel plating lightener, amagwiritsidwa ntchito kwambiri mumakampani opanga ma electroplating;③ Chofunika chochotsa dzimbiri: mowa wa proparynyl ndi mankhwala ake otsika amatha kuletsa dzimbiri, mkuwa, faifi tambala ndi zitsulo zina ndi zinthu za asidi monga acetic acid, phosphoric acid, sulfuric acid, hydrochloric acid;(4) Kukula kwamafuta: kutentha kwambiri, kuthamanga kwambiri komanso ndende ya hydrochloric acid corrosion inhibitors ndizomwe zimafunikira kwambiri pakupanga ma asidi amtundu wa corrosion inhibitors mumafuta ndi gasi Wells;⑤ angagwiritsidwe ntchito monga zosungunulira, chlorinated hydrocarbon stabilizer, fungicide ndi zipangizo zina.
Njira yopanga
Pakali pano, ambiri ntchito yokonzekera njira propargyl mowa kunyumba ndi kunja ndi zimene formaldehyde ndi acetylene kubala propargyl mowa ndi butynediol, amene propargyl mowa ndi byproduct wa butynediol.Ndi kusintha mulingo woyenera kwambiri kumwa mpweya wa acetylene, kusintha mmene kuthamanga, kudziwa bwino pH mtengo, chiŵerengero cha mowa propargyl ndi butynediol akhoza kufika 1:1.6, kuti patsogolo selectivity wa mowa propargyl.Njira: Onjezani chothandizira cha okosijeni mkuwa mu thanki yotsegulira, onjezerani madzi ofewetsa, gwedezani kwa mphindi 20, ndikutsanulira chisakanizo cha chothandizira ndi madzi mu thanki yosonkhezera ndi mpope.Madzi ofewa ndi formaldehyde adawonjezedwa mu thanki yotenthedwa kuti akonze yankho lomwe lili ndi 6% ~ 10% formaldehyde.The oyambitsa madzi amapopa mu riyakitala ndi plunger chakudya mpope malinga ndi kuyeza otaya mlingo, ndi acetylene kompresa anayamba kusintha acetylene otaya mlingo ndi kulamulira anachita liwiro.The basi kutentha ndi kuthamanga kulamulira dongosolo la riyakitala anayamba kulamulira kutentha kwa riyakitala pa 90 ~ 130 ℃ ndi mavuto pa (2.0 ± 0.1) MPa.Dongosolo lamachitidwe limazungulira pambuyo pa kukhetsa, ndipo kukhetsa kumabwerera ku thanki yogwedezeka.Zomwe zili mu formaldehyde zidadziwika pambuyo pa 0.5h.Pamene otsalira formaldehyde anali zosakwana 0,3%, mkombero anaimitsidwa ndipo yankho anachita anapopedwa mu thanki wapakatikati ndi propargyl ndi butanediol zili za 4% ndi 6%, motero.Chothandizira pakupanga chikuyenera kusinthidwa pafupipafupi, ndipo nthawi yosinthira ndi masiku 30 mpaka 40.Nayitrogeni amagwiritsidwa ntchito limodzi ndi chothandizira kuchotsa zinthu m'dongosolo panthawi yosintha.Pambuyo pa kupatukana ndi kusefera kwamphamvu, chothandizira chotsalira chimayikidwa mu tanki yosungiramo chothandizira ndikumata ndi madzi.Chothandizira chatsopanocho chalembedwanso mumzere wotsatira wa batching system.
Kusanthula kwa msika wa mowa wa Propargyl
Dezhou Tianyu Chemical Co., Ltd. ndi imodzi mwa ochepa zoweta kupanga propargyl mowa ndi butanediol mabizinezi lalikulu, linanena bungwe pachaka propargyl mowa 1200T, butanediol 2400T, ndi khalidwe la Germany BASF ofanana.Henan Haiyuan Fine Chemical Co., Ltd. adakweza ndikuwongolera ntchitoyo pamaziko a njira yoyambira yopanga Shandong Dongfang Le, ndikutulutsa kwapachaka kwa 1200T propionyl mowa ndi 2400T butanediol.Ku China, mowa wa proparynyl umagwiritsidwa ntchito kwambiri popanga mankhwala, sodium phosphate, calcium phosphate, sulfonamide ndi mankhwala ophera tizilombo, omwe amawerengera pafupifupi 60% ya okwana.Kupaka faifi tambala mwachangu ndi kung'anima kumafikira 17%.Kupanga mafuta pafupifupi 10%;Chigawo chachitsulo ndi pafupifupi 8 peresenti;Makampani ena amawerengera pafupifupi 5%.Mowa wa Propargyl ndi mankhwala oopsa kwambiri omwe amakhudzidwa ndi kupanga, kutsatsa komanso kugwiritsa ntchito.Ndi mankhwala otsika, mankhwala ophera tizilombo, medialurgical media ndi magawo ena othandizira kapena chimodzi mwazinthuzo.Pofika kumapeto kwa 2017, mphamvu zopangira zoweta zapakhomo zinali 4,770T /a, ndipo zofunidwa zinali pafupifupi 4,948T /a.Kupereka ndi kufunidwa kumakhala kokwanira, ndi kuchepa kwanthawi ndi nthawi.
Kumaliza
Pakali pano, mpikisano zoweta propanol msika ndi oopsa, ntchito munda wake waukulu ntchito ndi makampani mankhwala fosfomycin mndandanda mankhwala, ndi dziko maantibayotiki kuyang'aniridwa ndi ntchito electroplating chitetezo chilengedwe, owerenga propanol kumunsi kwa nthawi yochepa kwenikweni sanali kuwonjezeka.Pakalipano, tikuyesera kupititsa patsogolo njira yatsopano yochitira, nthawi zonse kusintha zokolola za mowa wa propargyl, ndi kuyesetsa kuchepetsa mphamvu ya mowa wa propargyl mowa.Kukhazikitsidwa kwa ntchitozi kudzachepetsanso mtengo wa mankhwala osokoneza bongo a propargyl, kuwongolera mpikisano wazinthu, ndikuyesetsa kukwaniritsa zofuna za msika wapakhomo ndi wakunja wa mowa wa propargyl ndi mndandanda wazinthu, kuti apange phindu lochulukirapo pazachuma komanso chikhalidwe.
