Caqabadaha Cabbirka Cufnaanta Gudaha
Kala-baxa cufnaanta ayaa dhibaato ku ah esterification-ka marxalado badan leh, taasoo keenta in daahirnimada linalyl acetate ay hoos uga dhacdo heerka GB 29985-2013. Isku-darka maxalliga ah, isbeddelka heerkulka, iyo isbeddellada quudinta reagent-ka ayaa qalloociya akhrinta cufnaanta, taasoo wiiqaysa xakamaynta falcelinta esterification-ka iyadoo la adeegsanayo mitirrada cufnaanta. Acetyl chloride si dhakhso ah ayay u weerartaa dusha sare ee dareemayaasha qoyan, gaar ahaan birta aan miridhku lahayn, taasoo keenta fashil degdeg ah. Kaliya jirka Hastelloy oo leh dahaarka PTFE ayaa hubiya mitirrada cufnaanta u adkaysta daxalka si loogu farsameeyo kiimikada iyadoo la adeegsanayo soo-gaadhista acetyl chloride ee joogtada ah.
Muunad qaadashada dufcaddii dhaqameed ma keeni karto la socodka falgalka kiimikada ee waqtiga dhabta ah ee isku-darka linalyl acetate. Ogaanshaha cilladaha dib u dhaca waxay horseedaa xad-dhaaf ah oo acetyl chloride ah iyo heerarka hydrogen chloride oo sarreeya, taasoo kicinaysa leexashada urta. Kala-soocidda wejiga oo aan ku filnayn marka la kala-saaro waxay sababtaa in quudka aan falcelinta lahayn uu wasakheeyo badeecada, taasoo hor istaagta la socodka heerka quudinta acetyl chloride iyo yareynta beddelka walxaha ceeriin.
Nidaamyada dareeraha gardarrada ah waxay carqaladeeyaan isgaarsiinta RS485 ee mitirrada cufnaanta warshadaha waxayna yareeyaan isku-darka calaamadaha 4-20mA ee deggan si loo xakameeyo habka.
