Cyanuric acid tranim (TAC) cov txheej txheem ntau lawm, los ntawm cov organic uas hnyav hauv tej yam kev mob uas tsis yog cov allyl chloride, cyanuric acid tri-sodium allyl chloride thiab cov tshuaj tiv thaiv ntawm allyl chloride tau raug tshem tawm ntawm kev sib tov cryogenic vacuo, nrog micro lim membrane separating thiab tshem tawm salts tsim, trisodium cyanurate ntawm ib qho mole ntawm allyl chloride siv 3.9 mus rau 6.0mol, thiab reacted at _5 ° C rau ib qhov kub thiab txias + cov ntsiab lus ntawm 50 ° C lossis ntau dua rau cov tshuaj tiv thaiv.
Cov tshuaj tiv thaiv zoo dua li ua tiav hauv ob theem, thawj theem tuav tus O mus rau + 20 ° C, qhov hloov ntawm 90 mus rau 95%, tswj qhov kub ntawm 30 txog 40 ° C nyob rau theem ob, qhov kev hloov pauv mus txog 100 %.
Cyanuric triallyl allyl chloride ntau lawm txoj kev siv ntau npaum li ntawm 99-100% ntawm qhov phaus ntawm cov tshuaj chev dawb huv. Tag nrho cov tshuaj tiv thaiv lub sij hawm tsis pub ntev tshaj 3 xuab moos tag nrho lub sij hawm tshwm sim yog lub sij hawm ntawm cov reactants thiab cov tshuaj tiv thaiv tom qab ntawm allyl chloride tau ntxiv rau lub sijhawm.
Raws li lub invention, ib mole ntawm allyl chloride siv trisodium cyanurate 3.9 rau 6.0mol ntawm. Txawm li cas los xij, ib zaug ntawm trisodium cyanurate siv yog li 4.9 mus rau 5.2 mo kuv ntawm allyl chloride.
Cov tshuaj tiv thaiv nruab nrab ntawm qhov xaiv ntawm qhov ntsuas kub yog _5 ° C thiab + 50 ° C, dua li ntawm O thiab 40 ° C. Txoj kev zoo dua li ob theem: Ntawm qhov no, thawj theem ntawm lub txee yuav tsum ua kom zoo dua ntawm qhov ntsuas kub tsawg + 5 mus + 10 ° C, qhov kev hloov dua siab tshiab yog 90 mus rau 95%; nyob rau theem ob, qhov tshuaj tiv thaiv zoo dua li +30 + 40 ° C raws li txuas ntxiv rau kev hloov siab ntawm 100%.
Thiaj li yuav ua rau tus neeg tsis sib haum xeeb (supplement) uas ua rau nws txo qis qis (uas ua rau kom muaj qoob loo), qhov tshuaj tiv thaiv ntawd tau sib xyaw kom sai, yog li sij hawm sib ntxiv rau feem ntau ntawm cov tshuaj tiv thaiv tsawg kawg. Tag nrho cov tshuaj tiv thaiv lub sij hawm (piv txwv li, tom qab qhov tshuaj tiv thaiv thiab qhov sib tov tshuaj yog siv lub sijhawm) yog li tsis pub ntau tshaj 3 teev, thiab nyiam dua tsawg dua 2 teev, tshwj xeeb tshaj yog kuv mus 1.5 teev.
Muab cov tshuaj tiv thaiv kab mob siab ua kom txaus, kom ua tiav cov sij hawm luv luv, nws yuav tsum tau muaj zog txias, piv txwv li, muaj cua txias nrog lub cua txias. Nyob rau ib qho kev lag luam, nws yog tshwj xeeb tshaj tawm txoj kev tawm ntawm cua sov los ntawm sab nraud Circuit Court Circuit muaj ib qho kev hloov hluav taws xob thiab cov twj tso kua mis.
Tom qab qhov tshuaj tiv thaiv, tom qab tas li ntawm ib qho kev tsim polymerization inhibitor (hydroquinone derivative feem ntau yog) nyob rau hauv cov tshuaj sib tov sib xyaw, cov khoom ntab ntawm 40 mus rau 50 ° C thiab maj mam distilled hauv kev txo qhov siab. Tom qab distillation TAC 40 ua cov kua rau 50 ° C, khoom sodium chloride, thiab cov tshuaj tsis siv tshuaj sodium chloride TAC, TAC muab cov yeeb yaj kiab meej thiab cov yeeb yaj kiab centrifuge los ntawm lub membrane tetrafluoroethylene. Tawm los tau ntau tshaj 95%, TAC tau nrog purity muaj tsawg kawg yog 99.5%, APHA tus O ntawm 10, thiab ntau dua los yog sib npaug zos rau qhov chaw txias 27 ° C.
Cov khoom siv tshuaj: xaiv cov tshuaj lom neeg muaj tshuaj lom neeg feem ntau hauv qhov chaw ntawm allyl chloride allyl cawv, allyl chloride thiab allyl cawv muaj qhov taw tes kub tshaj qhov tsawg tshaj li qhov yuav tsum tau pom tias tsawg-kub nqus cov hmoov sib xyaw kom rov zoo, kom tsis txhob muaj kev kub ntxhov. Trisodium cyanurate xaiv es tsis txhob cyanuric chloride, cyanuric chloride yog tsis ruaj tsis khov hauv huab cua, tsis muaj zog, corrosive thiab irritant, nws yog ib qho muaj zog lachrymator; thiab trisodium cyanurate, raws li lub ntsev tsis muaj ntsev, tsis txhuam thiab khaus. Cov kev hloov ntawm cov neeg ua haujlwm raw cov neeg ua hauj lwm tuaj yeem paub txog kev khiav hauj lwm ib puag ncig, txo qhov raug mob mus rau ib puag ncig.
Cov kua nplaum-dawb: Cov kaus dej tau ntxiv ib qho me me dhau los ntawm allyl chloride, allyl chloride nyob rau hauv ntau dhau heev lawm kom paub meej cov tshuaj tiv thaiv kab mob cyanuric acid trisodium, . Allyl chloride yog kua nyob rau ntawm chav tsev kub, trisodium cyanurate hmoov qhuav hauv chav tsev, ua kua tshuaj ncaj qha ras, organic reagent los yog tsis txhob siv cov dej ua kua, ua kom tsis muaj cov kauj ruam tom qab sib cais.
Cov txheej txheem qes dej kub tsis zoo: trisodium cyanurate, allyl chloride thiab cov tshuaj tiv thaiv tau ua kom cov kua qoob loo sib tov ua kom txau deb, cov cua kub kom txias 35-40 ° C, kom cov pob txha uas tsis zoo yuav tsum tau muab pov tseg, tsis txhob cyanuric acid ntawm kom siab kub triallyl daj, txhim kho purity thiab tawm los triallyl cyanuric acid.
Nruam cov membrane filtration purification process: triallyl cyanuric acid yog kua ntawm 35_40 ° C, khoom sodium chloride, thiab sodium chloride yog insoluble cyanuric acid triallyl. Cov cyanuric chloride thiab triallyl sib tov nyob hauv lub lauj kaub, ntxiv mus rau hauv lub centrifuge tetrafluoroethylene membrane, triallyl cyanuric acid filtration membrane los ntawm 0.1 micron tetrafluoroethylene yuav ua rau pom tseeb thiab los ntawm cov kab cyanuric chloride, triallyl thiab industrial crude, txo cov kwj dej, kev siv dej thiab dej khib nyiab, kom tau txais kev txuag hluav taws xob.
Muab piv rau daim duab dhau los, cov teebmeem ntawm lub sijhawm tshiab no yog:
(1) nyob rau hauv cov tshuaj tiv thaiv tau muab tshem tawm uas siv cov kua qaub rau hauv cov tshuaj tiv thaiv tuaj yeem ua tiav nyob rau lub sij hawm luv luv, thiab kev tswj kev sov tsis tseem ceeb rau kev xav tau, tus APHA ntxiv xim yuav tsum raug qis dua (piv txwv li, 10 lossis tsawg dua ) uas ua rau TAC purity muaj li ntawm 99%, tus qoob loo ntawm ntau tshaj 95% .Tom qab cov tshuaj tiv thaiv thiab cov khoom sib thooj, cov TAC muaj cov kua ntsev ceev nrooj sib cais, tsis tas ua rau muaj teeb meem, thiab tau txais cov tshuaj chloride rov qab siv dua tsis txo cov zoo ntawm TAC;
(2) piv rau txoj kev paub tam sim no, txoj kev ua raws li qhov tsim muaj kev yoojyim rau kev siv, nrog rau theem qis ntawm kev nyuaj ntawm qhov uas yuav tsum tau muaj, vim qhov teeb meem tsis muaj theem sib cais thiab dej ntxuav ruam;
(3) txhim kho cov khoom muaj nqis, txo cov khoom siv raw ntoo, txo cov kauj ruam ntawm cov kauj ruam uas ua haujlwm nyob rau ntau txoj hauv kev ua ub no, txuag hluav taws xob thiab kev pab cuam, txo cov khoom pov tseg.
