Definition and Usage Areas of Butanone
Butanone can be produced by the oxidation of 2-butanol. Dehydrogenation A is catalyzed by a 2-butanol catalyst using copper, zinc, or bronze:
CH 3 CH (OH), CH 2 , CH 3 → CH 3 C (O) CH 2 CH 3 + H 2
This is used to produce about 700 million kilos per year. Other syntheses studied but not implemented are the Wacker oxidation of 2-butene and the oxidation of isobutylbenzene; this is analogous to the industrial production of acetone. [5]
Both the liquid phase oxidation of heavy naphtha and the Fischer-Tropsch reaction produce mixed oxygenate streams; from there 2-butanone is extracted by fractionation. [7]
Butanone is biosynthesized by some trees and is present in small amounts in some fruits and vegetables. Released into air from car and truck exhausts
Methyl Ethyl Ketone is a ketone type active organic solvent. In systems containing phenolic, alkyd, vinyl resin, in cellulosic systems; Used in paint removers and adhesives. It is also used in professional cleaning and care products for the food and beverage industry.
Usage areas
Butanon, etkili ve yaygın bir çözücüdür [ve zamklar , reçineler , selüloz asetatve nitroselüloz kaplamalar ile vinil filmlerdeki işlemlerde kullanılır. Bu nedenle, plastik, tekstil, parafin mumu üretiminde ve cila , cila , boya sökücü, denatüre alkol , yapıştırıcılar için bir denatüre edici madde ve temizlik gibi ev eşyalarında kullanılmaktadır. ajan. Bu benzer çözücü özelliklere sahip asetonancak daha yüksek sıcaklıkta kaynar ve buharlaşma oranı önemli derecede yavaştır. Asetonun aksine, suyla bir azototrop oluşturur , bazı uygulamalarda nemin azeotropik damıtımı için yararlıdır. Butanone, silinen boya çözücüsü olarak kuru silme işaretçilerinde de kullanılır .
Butanone is sold as “model cement” for use as fittings for scale model kits when melting polystyrene and many other plastics. Although often thought of as sticky, it actually functions as a sourcing agent in this context.
Butanone is the precursor to methyl ethyl ketone peroxide, which is a catalyst for some polymerization reactions such as cross-linking of unsaturated polyester resins.
