Nyanzvi mukugadzira propargyl doro, 1,4 butynediol uye 3-chloropropyne.
Propargyl doro rekugadzira maitiro uye kuongororwa kwemusika
Zvivakwa uye mashandisirwo e2 propargyl doro
2.1 Yakanakisa basa repamusoro uye kupararira
Propargyl doro ane simba polarity uye hydrophilicity, nokuti rine -OH, uye hydrophobicity imhaka yokuti rine hydrocarbon boka, nokuti zvivako izvi kuita propargyl doro seasiri-ionic surfactant, kuratidza kushanda zvakanaka, pamwe yakanaka yakaderera furo, defoaming uye wettability.Mazhinji ekunyorova maajenti anotubuka zviri nyore, nepo makemikari akawanda ekubvisa foaming maajenti asina kunyorova.Zvichienzaniswa nemamwe ma surfactants, maalkyl alcohols ane huremu hudiki hwemamorekuru, kupararira kuri nyore, kupararira kwakanaka, kunyorova kwakanaka uye furo rakaderera.Kune rimwe divi, maalkyl alcohols ane hydrocarbon base branched chain groups, kazhinji mapoka madiki (kazhinji methyl), kune maviri mapoka epolar muchimiro.Nekuda kwechimiro ichi chemakemikari, maalkyl alcohols ane yakanaka wettability.Kune rimwe divi, cheni dzealkyl-branched mupropargyl doro dzinogona kuderedza kukwezvana pakati pemamorekuru akavakidzana uye kugadzira firimu rinowedzera uye rinofema pamuganhu wegasi-mvura.Naizvozvo, haingoiti chete furo pachayo, asiwo ine humwe hunyanzvi hwekubvisa furo, uye inogona kusanganiswa nemamwe maajenti ekusvibisa kuita basa rakakura.
2.2 Yakanakisa simbi corrosion inhibition
Parizvino, iyo simbi corrosion inhibitors inoshandiswa mune acidic midhiya inowanzova organic komisheni, ine yakasimba adsorption kugona pane simbi.Iyo molecular chimiro chepropargyl doro rinosanganisira mapoka epolar uye mapoka asiri-polar.Iri adsorbent ye organic corrosion inhibitors.Kune rimwe divi, zvisungo zvekubatanidza zvinoumbwa pakati pepropargyl doro nemaatomu esimbi zvinosimudzira kushambadza kwedoro kusvika kumwero wakati.Panguva imwecheteyo, iyo PI bond mu propargyl alcohol molecule inopera simba, iyo katatu bond inogadziriswa, uye polar hydroxyl boka riri pedyo neacetylene bond, iyo inowedzera adsorption.Mune alkaline svikiro, proparynyl doro rinogona kupinza Langmuir pane yakachena aluminium, ine yakanaka corrosion inhibition effect.Propargyl doro imhaka yekuita kwayo kwakanakisa, ine huwandu hwakawanda hwekushandisa, inonyanya kushandiswa mumishonga yepakati, mhangura kana nickel plating polish, pesticide yepakati.Uye zvakare, propargyl doro rinogonawo kushandiswa se corrosion inhibitor yekushisa kwepamusoro, kudzvanywa kwepamusoro uye yakakwira hydrochloric acid mumafuta uye gasi rechisikigo Wells.
2.3 Kushandiswa kwepropargyl doro
① Yakakosha yepakati mune organic synthesis: muindasitiri yemishonga, proparynol yakakosha yepakati sodium fosfomycin, calcium fosfomycin, sulfadiazine, uye inoshandiswawo mukugadzira allyl doro, acrylic, vhitamini A uye zvimwe zvigadzirwa zvemishonga;② Electroplating indasitiri inopenya: propargyl doro makomisheni ane yakanaka kufanana uye kupenya, uye yakanaka mwenje kuramba mu nickel plating.Chizvarwa chechina nickel plating inopenya, inoshandiswa zvakanyanya muindasitiri ye electroplating;③ Yakakosha kubvisa ngura: doro reproparynyl uye maumbirwo ayo epasi anogona kutadzisa kukora kwesimbi, mhangura, nickel uye mamwe masimbi neasidhi zvinhu zvakaita seacetic acid, phosphoric acid, sulfuric acid, hydrochloric acid;(4) Petroleum kukura: tembiricha yepamusoro, kumanikidzwa kwakanyanya uye yakakwira hydrochloric acid corrosion inhibitors ndiwo akakosha anoshanda zvikamu zveanoshanda zvakanyanya acid corrosion inhibitors mumafuta uye gasi Wells;⑤ inogona kushandiswa se solvent, chlorinated hydrocarbon stabilizer, fungicide uye zvimwe zvigadzirwa.
Nzira yekugadzira
Parizvino, iyo inonyanya kushandiswa nzira yekugadzirira yepropargyl doro kumba nekune dzimwe nyika ndeyekuita kwe formaldehyde uye acetylene kubudisa propargyl doro uye butynediol, iyo propargyl doro inokonzerwa nebutynediol.Nekugadzirisa iyo yakakwana yekutora vhoriyamu yeacetylene gasi, kunatsiridza kudzvanywa kwekuita, kuona yakanakisa pH kukosha, chiyero chepropargyl doro uye butynediol inogona kusvika 1: 1.6, kuitira kuti uvandudze kusarudzwa kwepropargyl doro.Maitiro: Wedzera copper oxygenated catalyst mu activation tank, wedzera mvura inopfava, simbisa kweinenge 20min, uye dururira musanganiswa wecatalyst nemvura mutangi inomutsa nepombi.Mvura yakapfava uye formaldehyde yakawedzerwa kune tangi yakamutswa kugadzirira mhinduro yakamutswa ine 6% ~ 10% formaldehyde.Mvura inomutsa yakapombwa mureactor ine pombi yeplunger yekudyisa zvinoenderana neyakayerwa kuyerera, uye iyo acetylene compressor yakatanga kugadzirisa acetylene kuyerera uye kutonga kumhanya kwekuita.Iyo otomatiki tembiricha uye kudzvanywa kudzora system ye reactor yakatanga kudzora tembiricha yeiyo reactor pa 90 ~ 130 ℃ uye kudzvanywa kuri (2.0±0.1) MPa.Iyo reaction system inotenderera mushure mekubuda, uye kubuda kunodzokera kune yakamutswa tangi.Izvo zvirimo zve formaldehyde mune izvo zvakaonekwa mushure me 0.5h.Apo iyo yakasara ye formaldehyde yakanga iri pasi pe 0.3%, kutenderera kwakamira uye mhinduro yemhinduro yakakandwa mutangi repakati nepropargyl uye butanediol zviri mukati me4% uye 6%, maererano.Iyo catalyst mukugadzira maitiro inoda kutsiviwa nguva nenguva, uye nguva yekutsiva ndeye 30 kusvika 40 mazuva.Nitrogen inoshandiswa pamwe chete necatalyst kubvisa zvinhu kubva muhurongwa panguva yekutsiva.Mushure mekuparadzaniswa nekudzvanywa kwefiltration, iyo yakasara inokonzeresa inoiswa mune yakashandiswa catalyst yekuchengetedza tank uye yakavharwa nemvura.Iyo itsva catalyst inonyorwa kumashure muchikamu chinotevera cheiyo batching system.
Propargyl doro rekuongorora musika
Dezhou Tianyu Chemical Co., Ltd. ndeimwe yevashoma kugadzirwa kwemba kwepropargyl doro uye butanediol mabhizinesi mahombe, gore negore kubuda kwepropargyl doro 1200T, butanediol 2400T, uye mhando yeGermany BASF yakaenzana.Henan Haiyuan Fine Chemical Co., Ltd. yakakwidziridza uye yakakwenenzvera chirongwa ichi pahwaro hwekutanga kugadzirwa kweShandong Dongfang Le, ine gore negore kubuda kwe1200T propionyl doro uye 2400T butanediol.MuChina, proparynyl doro rinonyanya kushandiswa mukugadzirwa kwezvinodhaka, sodium phosphate, calcium phosphate, sulfonamide uye mishonga yezvipembenene, inoverengera inenge 60% yehuwandu.Rapid nickel plating uye flash plating yakaverengera 17%.Kugadzirwa kwemafuta kunenge 10%;Chikamu chesimbi chinenge 8 muzana;Mamwe maindasitiri anoita 5%.Propargyl doro ikemikari ine muchetura inonzwa kugadzirwa, kushambadzira uye kushandiswa.Mushonga wepasi pemvura, mushonga wezvipembenene, metallurgical media uye mamwe minda yekubatsira kana chimwe chezvikamu.Kubva pakupera kwa2017, iyo inoshanda yekugadzira mudzimba simba yaive 4,770T /a, uye iyo yaidiwa yaive ingangoita 4,948T / a.Kupihwa uye kudiwa kwakanyatso kuenzana, neapo neapo kushomeka.
Anopedzisa
Parizvino, makwikwi emusika wemumba wepropanol anotyisa, nzvimbo yayo huru yekushandisa iindasitiri yemishonga fosfomycin yakatevedzana zvigadzirwa, neiyo yenyika inorwisa mabhakitiriya ekutarisa uye electroplating indasitiri yekudzivirira kwezvakatipoteredza, vashandisi vepasi pemvura munguva pfupi havana kuwedzera.Parizvino, isu tiri kuyedza kuwedzera optimize maitiro matsva ekuita, kugara tichivandudza goho repropargyl doro, uye kuyedza kudzikisa simba rekushandisa kwepropargyl doro zvigadzirwa.Kuitwa kwemabasa aya kuchawedzera kuderedza mutengo wezvigadzirwa zvedoro, kuvandudza kukwikwidzana kwezvigadzirwa, uye kuedza kuzadzisa kudiwa kwemusika wepamba uye wekunze wepropargyl doro uye nhevedzano yezvigadzirwa, kugadzira mamwe mabhenefiti ehupfumi nemagariro.
