liquid resin

Polythene is formed by the addition polymerization of multiple monomers of ethylene or ethene. When liquid ethylene is polymerized at high temperature and pressure, a resin of polyethylene is obtained. It can be melted spun or moulded as desired. Note that in addition polymeriza..

Methanol CH 3 OH also known as wood alcohol can be produced by destructive distillation of wood. Today methanol is chemically produced by catalytic hydrogenation of carbon monoxide at high pressure and temperature and in presence of Cu, Zn, Cr 2 O 3 catalys..

Shape-selective catalysis are those reactions that depend on the pore structure of the catalyst and the size of the reactant and product molecules. In such reactions, zeolites are used as catalysts. Zeolites are microporous aluminosilicates of the general formula M x / n [(AlO 2 ) x (SiO 2 ) y ].z ..

>Zeolites as ion-exchange materials have been replaced by synthetic cationic and anionic exchange resins, but their use as selective adsorbents for gases or liquids is extensive. The zeolites act as molecular sieves for the reactants. To achieve this, zeolites are heated in vacu..

3 COOH) It is the main constituent of vinegar and is obtained by fermentation of molasses in the presence of air. Industrially, it is obtained by oxidation of ethanol with air in the presence of cobalt acetate catalyst. Ethanoic acid a colorless liquid with a pungent odor boils..
