The present invention provides a novel process to recover a high strength Calcium Hypochlorite from aqueous waste water stream by selective crystallization of sodium chloride and calcium hypochlorite by changing process parameters such as pressure, temperature, mixing etc. The main advantage of the present inventio...

The present invention deals with recovery of mono-ols and polyols of aliphatic and water-soluble aromatic compounds from their corresponding acetals / ketals. Recovery of mono-ols and polyols from the acetals / ketals is considered to be difficult because of possibility of polymerization of aldehydes / ketones durin...

The present invention deals with separation of mono-ols polyols from the aqueous stream by reactive extraction technology. In many of the chemical processes, mono-ols and polyols remain in the aqueous phase. Because of their high solubility in water, separation of these compounds is difficult. The conventional metho...

1. The GASCT process for recoM.-iyseparat.ioii of alkali metal by non-evaporative method comprises of crystallization by using Antisolvents exhibiting critical solution temperature phenomenon such as e.g. Triethyl amine (TF,A), Diisopropvl amine (DIPA). 2-Buloxy Bthanol. Isobutyric Acid, Methanol, Fthanol. Tetrahvdr...

A process of manufacturing stable bleaching powder having more than 35% available chlorine, comprising the steps of Chlorination of calcium hydroxide to obtain a composite mixture of calcium hypochlorite, calcium hydroxide and calcium chloride; Washing the composite mixture obtained in step a) with calcium chloride ...
