PURPOSE:To utilize energy effectively, by using a waste from a distilling column partically for diluting raw material molasses, and using the concentrate of the remaining waste as a fuel for a steam generating apparatus. CONSTITUTION:Molasses 2, diluting water 3 and an acid 4 are mixed in a ...
The process for the preparation of the ethyl alcohol from fermented mash consists in that the mash fermented at the temperature of 32°C is pre-heated up to a temperature of 58...62°C, by receiving heat from the alcohol vapours coming from a dephlegmator, then it is heated to the tem...
ethanol. The reaction temperature of caustic potash and alcohol is preferably 20-50 deg.C and that of the acetylene adduct and estrone is preferably -5-+10 deg.C. The amounts of caustic potash and the alcohol is 4- 30mol and 2-15mol, per 1mol of estrone, respectively. 展开 ...
Ethanol (alcohol, ethyl alcohol) is widely available as a beverage, is an important constituent of cosmetics, aftershave, hair tonic, antiseptics, mouthwashes, dishwashing detergents and glass cleaners, and is commonly used as an industrial solvent. Ethanol burns in air with a blue flame, formin...
A novel catalyst for hydration of ethylene to ethyl alcohol comprises active synthetic silicon dioxide as a base having deposited thereon natural kieselguhr and phosphoric acid. The catalyst is prepared by precipitative silicon dioxide from sodium silicate with hydrochloric acid, filtering the precipitate...
PURPOSE:To obtain the titled compound useful as an intermediate for drugs in high yield, by reacting a tertiary alcohol with a nitrile in defined specific molar ratios of the nitrile to the tertiary alcohol, an acid as a catalyst to the tertiary alcohol, and water to it. CONSTITUTION:In pre...

(1.91% vs. 7.53%, respectively). On contrary, the PGLS combination showed an antagonistic effect with synergistic factor less than 1.00 (Table5). Moreover, the deltamethrin control treated group (1 μl/ml) showed results similar to that of 70% ethyl alcohol control treated one. Meanwhile, ...
Here, we report a novel comparative assessment of preparation and characterization of thyme oil nanoemulsion and its chitosan encapsulation using high energy approach for the management of three major mosquito species viz., Anopheles stephensi (Liston,19
CONSTITUTION:A desensitizer such as quaternary ammonium or polyethylene glycol is mixed with a water-soluble polar solvent such as methyl alcohol, ethyl acetate or dioxane in a concn. of about 10-90%. Yeast belonging to the genus Saccharomyces, Endomyces or Lipomyces are dispersed in a ...
