This invention provides a composition of insulating fluid and process for the preparation thereof that mainly contains alkyl benzenes. In addition to alkyl benzenes, the composition also contains an antioxidant, an antifoaming agent, a pour point dispersant, a corrosion inhibitor and a detergent-dispersant additive. The product of this invention has utility as an insulating fluid in electrical installations such as transformer.

Composition of insulating fluid and process for the preparation thereof

The present invention provides a process for the preparation of ethanol from starch. Specifically, the present invention provides a process for the preparation of ethanol from starch such as tapioca, potato, sweet sorghum, rice by liquification and saacharification of starch and subsequent fermentation of mono saccherides to ethanol in presence of thermophilic micro-organisms.

The present invention provides a process for the preparation of p-toluic acid by liquid phase oxidation of p-xylene using oxygen or air as oxidant in the presence of p-toluic acid, water as solvent and cobalt salt or its combinations with salts of Ce, Mn as catalyst. Oxidation is carried out at 130-190&#xb0; C. and pressure sufficient to keep water in liquid state. Oxidation step is followed by filteration to obtain p-toluic acid as major product. Untreated p-xylene is recovered and recycled and the catalyst is recovered from aqueous phase and is recycled.
