Umlinganiselo woxinano oluphakathi kwi LinalylAisetateSukwenziwa kwezinto
Ukulinganiswa koxinano oluphakathi kubalulekile ekujongeni impendulo yamakhemikhali kwi-linalyl acetate synthesis, apho ukwahluka koxinano kuchaphazela ngokuthe ngqo ulawulo lwempendulo ye-esterification. Ukuhlolwa okuqhubekayo ngexesha langempela kuzinzisa umlinganiselo wokutya we-linalool kunye ne-acetyl chloride, kuphucula ukuguqulwa kwezinto eziluhlaza kunye nokunciphisa inkunkuma ye-solvent. Ukuthintela ngokuzenzekelayo i-acetyl chloride overdosage kusetyenziswa iimitha zoxinano oluphakathi kunciphisa ukwakheka kwe-HCl engaphezulu, kuqinisekisa ulawulo oluzinzileyo lwevumba le-hydrogen le-chloride kwiimveliso zeziqholo.
Iimitha zoxinano lweefolokhwe zokulungisangemizimba yeHastelloy kunye ne-PTFE lining zimelana nezinyibilikisi ze-anhydrous organic kwaye zimelana nokugqwala kwe-acetyl chloride, zigcina ukuthembeka kwesignali kulawulo lwenkqubo. Unxibelelwano oludibeneyo lwe-RS485 kunye nemveliso yesignali ye-4-20mA zixhasa ukudluliselwa kwedatha ngaphandle komthungo kwii-PLC zemveliso, okuvumela ukubonwa okungaqhelekanga kwangoko kunye nokuziqhelanisa nokusabela. Oku kuchaneka kolawulo lwenkqubo kuqinisekisa ukuthotyelwa kwemigangatho yomgangatho we-linalyl acetate (GB 29985-2013) kwaye kwandisa ukusebenza kakuhle kwemveliso ukuya kuthi ga kwi-30%.
Isishwankathelo seEukuqinisekiswa kwe-sterilizationLinalool
Ukwenziwa kwe-linalool esterification rhoqo nge-acetyl chloride kwi-anhydrous organic solvents kuvelisa i-linalyl acetate, icandelo eliphambili lesiqholo. Le nkqubo ifuna ukubekwa esweni ngokuchanekileyo kwesantya sokutya kwe-acetyl chloride ukulawula i-reactant stoichiometry kunye nokunciphisa ivumba le-chloride hydrogen kwiimveliso zeziqholo. Iimitha zoxinano oluphakathi—ezilungiselelwe i-0.890–0.894 g/cm³ ekupheleni kwe-distillation—zibonelela ngokubekwa esweni kwempendulo yeekhemikhali ngexesha langempela, zixhasa ulawulo lwenkqubo oluzenzekelayo kunye nemigangatho yomgangatho we-linalyl acetate (GB 29985-2013).
Imveliso evela kwi-reactor ingena kwicandelo lokunyibilikisa, apho iimitha zoxinano ezimelana nokugqwala zeLonnmeter ezine-Hastelloy kunye ne-PTFE lining ziqinisekisa ukuthembeka komlinganiselo kwiindawo ezishushu ze-acetyl chloride atmospheres. Xa uxinano lubonisa i-linalyl acetate ecocekileyo, iinkqubo zeevalvu ezizenzekelayo ziqondisa imveliso ekuqokelelweni, ziyisahlula kwimixube engaphendulwanga enoxinano oluphantsi. Le mixube iphinda isetyenziswe ngokuzenzekelayo ngolawulo lweevalvu ukuphucula ukuguqulwa kwezinto eziluhlaza kunye nokunciphisa inkunkuma, okwandisa ukusebenza kakuhle kwemveliso ngaphezulu kwe-30%.
Unxibelelwano oludibeneyo lwe-RS485 kunye neziphumo zesignali ze-4-20mA zibonelela ngokubekwa esweni kwenkqubo rhoqo kunye nokufunyanwa kwezinto ezingaqhelekanga, zixhasa amanyathelo okulungisa ngokukhawuleza kwaye zinciphise ukuphambuka kumgangatho wemveliso. Ukuhlanganiswa okungenamthungo kweemitha zoxinano olungaphakathi kuphucula ukusetyenziswa kwe-solvent kwaye kugcina iimeko ezingenamanzi ezibalulekileyo kulawulo lokuphendula kwe-esterification.

Imingeni ekuLinganisweni koXinaniso oluPhakathi
Ukuxinana koxinano kuchaphazela i-esterification yezigaba ezininzi, nto leyo ebangela ukuba ubumsulwa be-linalyl acetate buye phantsi komgangatho we-GB 29985-2013. Ukuxubana kwendawo, utshintsho lobushushu, kunye nokuguquguquka kokutya kwe-reagent kuguqula ukufundwa koxinano, nto leyo ethintela ulawulo lokuphendula kwe-esterification ngeemitha zoxinano. I-Acetyl chloride ihlasela ngokukhawuleza iindawo ezimanzi ze-sensor, ingakumbi intsimbi engatyiwayo, nto leyo ebangela ukungasebenzi kakuhle kwangaphambi kwexesha. Kuphela zii-Hastelloy bodies ezine-PTFE lining eziqinisekisa iimitha zoxinano ezingamelani nokugqwala ukuze kucutshungulwe iikhemikhali phantsi kokuvezwa okuqhubekayo kwe-acetyl chloride.
Ukuthatha iisampulu zebhatshi zemveli akunakubonelela ngovavanyo lwempendulo yeekhemikhali ngexesha langempela kwi-linalyl acetate synthesis. Ukufunyanwa kwe-anomaly okulibazisekileyo kukhokelela kwi-acetyl chloride overdosage kunye namanqanaba aphezulu e-hydrogen chloride, okubangela ukuphambuka kwevumba. Ukwahlulwahlulwa kwesigaba okungonelanga ngexesha lokucocwa kwemveliso kubangela ukuba i-feedstock engaphendulwanga ingcolise imveliso, nto leyo ethintela ukubekwa kweliso kwisantya sokutya kwe-acetyl chloride kunye nokunciphisa ukuguqulwa kwezinto eziluhlaza.
Iinkqubo ze-solvent ezirhabaxa ziphazamisa unxibelelwano lwe-RS485 kwiimitha zoxinano lwemizi-mveliso kwaye ziphazamisa ukuhlanganiswa kwesignali okuzinzileyo kwe-4-20mA ukulawula inkqubo. Ukungazinzi kwesignali okuqhubekayo kuthintela ukujonga inkqubo ngokuqhubekayo kunye nokuchongwa okungaqhelekanga, kuthintela inzuzo yokusebenza kakuhle kwemveliso kwaye kuthintele ukuthotyelwa kwemigangatho yomgangatho we-linalyl acetate.
Iingenelo zokudibanisa iiMeter zoxinano oluphakathi
Ulawulo loxinano lwexesha langempela luzenzekela ngokuzenzekelayo ukusebenza kwevalvu kumanqanaba okwahlukana, lunyusa isivuno se-linalyl acetate ngaphezulu kwe-30% xa kuthelekiswa neendlela ezisekwe kwi-batch. Iimitha ezikwi-inline ziphawula ngokukhawuleza i-acetyl chloride overdosage, zithintela ukwakheka kwe-HCl egqithisileyo kwaye zigcina ulawulo oluchanekileyo lwevumba le-chloride hydrogen kwiimveliso zeziqholo. Iimitha zoxinano ze-cylindrical ezinemizimba ye-Hastelloy kunye ne-PTFE lining zimelana nokugqwala kwe-acetyl chloride, zixhasa ukujonga impendulo yekhemikhali ixesha elide kwi-linalyl acetate synthesis. Imiqondiso edibeneyo ye-RS485 kunye ne-4-20mA inika idatha yenkqubo ezinzileyo nechanekileyo kwiinkqubo ze-PLC okanye ze-DCS phantsi kweemeko zekhemikhali ezirhabaxa. Impendulo eqhubekayo ekwi-inline ikhulisa ukuguqulwa kwe-feed linalool kunye ne-acetyl chloride, inciphisa inkunkuma yezinto eziluhlaza kwimveliso ye-ester kwaye iphucula rhoqo ubumsulwa bemveliso ngaphezu kwe-95%. Ukubeka iliso koxinano oluzenzekelayo nolulandelekayo kuxhasa ukuthotyelwa kwemigangatho yomgangatho we-GB 29985-2013 ye-linalyl acetate, nokuba kwiinkqubo kusetyenziswa izinyibilikisi ze-anhydrous organic.
Cela isicatshulwa semitha yoxinano lwe-Lonnmeter ukuze kujongwane nolawulo lwempendulo ye-esterification ngeemitha zoxinano kwi-linalyl acetate synthesis. Qinisekisa ukuba ubeka iliso kwisantya sokutya kwe-acetyl chloride ukuze kuthintelwe ukugqithiswa kwe-acetyl chloride kunye nevumba le-hydrogen le-chloride elingafunekiyo kwiimveliso zeziqholo.
