Sharaxaada
Dibutyl phthalate, sidoo kale loo yaqaan dibutyl phthalate ama dibutyl phthalate, Ingiriis: Dibutylphthalate, waa dareere saliid leh oo hufan oo aan midab lahayn oo leh culeys gaar ah oo ah 1.045 (21 ° C) iyo barta karkarinta 340 ° C, aan milmin biyaha, biyaha ku milma iyo isbeddelka, laakiin guryaha ayaa si fudud u xaliya. ether, acetone iyo benzene, iyo sidoo kale waa la qallafsan yahay inta badan hydrocarbons. Dibutyl phthalate (DBP), dioctyl phthalate (DOP) iyo diisobutyl phthalate (DIBP) waa seddexda caagadaha ugu caansan, kuwaas oo kala ah balaastikada, caag synthetic iyo maqaar macmal ah, iwm. caagadaha sida caadiga ah loo isticmaalo. Waxaa lagu helaa esterification kulaylka ee anhydride phthalic iyo n-butanol.
Guryaha Kiimikada
dareere saliid leh oo hufan oo aan midab lahayn oo leh ur yar oo udgoon. Ku milma dareerayaasha organic caadiga ah iyo hydrocarbons.
Codsiga
-Waxa loo isticmaalaa sidii balaastiiste loogu talagalay nitrocellulose, cellulose acetate, polyvinyl chloride, iwm. Alaabtani waa caag. Waxay leedahay awood kala diris xoog leh oo leh resins kala duwan.
-Waxaa loo isticmaalaa farsamaynta PVC, waxay siin kartaa jilicsanaanta wanaagsan ee alaabta. Maaddaama ay tahay mid raqiis ah oo socodsiinteeda wanaagsan, aad ayaa loo isticmaalaa, ku dhawaad u dhiganta DOP. Si kastaba ha ahaatee, isbeddelka iyo soo saarista biyuhu waa kuwo aad u weyn, sidaas darteed cimri dhererka alaabtu waa mid liidata, isticmaalkeedana waa in si tartiib tartiib ah loo xaddidaa. Alaabtani waa balaastiiste heersare ah oo nitrocellulose ah waxayna leedahay awood gelling oo xoogan.
-Waxaa loo isticmaalaa daaha nitrocellulose, waxay leedahay saameyn jilicsan oo aad u wanaagsan. Degenaansho heer sare ah, iska caabin dabacsanaan, dhejis iyo caabbinta biyaha. Intaa waxaa dheer, sheyga waxaa loo isticmaali karaa sidii caag ah oo loogu talagalay polyvinyl acetate, resin alkyd, ethyl cellulose iyo neoprene, iyo sidoo kale waxaa loo isticmaali karaa samaynta rinji, dhejisyada, maqaarka macmalka ah, khadadka daabacaadda, muraayadda badbaadada, celluloid, midabada, sunta cayayaanka, dareeraha udgoonka, saliidaha dharka, iwm.
- Sida caaga ah ee ester cellulose, milix iyo caag dabiici ah, polystyrene; si ay u sameeyaan polyvinyl chloride iyo copolymers ay qabow u adkeysi u synthesis organic, daro electrode xulashada ion, dareeraha, cayayaanka, balaastiigiyeyaasha, Gaaska chromatography dareere taagan (isticmaalka ugu badan ee heerkulka 100 ℃, dareeraha waa acetone, benzene, dichloromethane, ethanol), xajinta udgoon xeryahooda iyo seben. xeryahooda iyo xeryahooda kala duwan oo ogsijiin-ku jira (alkolada, aldehydes, ketones, esters, iwm).
