----- AIR POLLUTION TRANSLATIONS: A BIBLIOGRAPHY WITH ABSTRACTS - VOLUME 1 INTRODUCTION This volume of Air Pollution Translations: A Bibliography with Abstracts is the first document in a continuing series of compilations presenting abstracts and indexes of translations that have been analyzed and accessioned by the Air Pollution Technical Information Center (APTIC).DR ANTHONY MELVIN CRASTO Ph.D « New Drug The combined dichloromethane extracts are washed with cold saturated sodium chloride solution (1×30.0 mL) and dried over anhydrous sodium sulfate. Removal of solvent on a rotary evaporator with a water bath temperature of 45°C, gives a dark orange brown viscous liquid. To this viscous liquid, 80-85.0 mL dry toluene is added.Development of gel extraction process for Aloe vera grade dark brown viscous decolorization and purification oilGowda et al., (1979) reported that after harvest of Aloe vera leaf, the viscous pseudoplastic nature of Aloe vera gel, mainly due to the presence of polysaccharides composed of a mixture of acetylated glucomannans was lost shortly after extraction, apparently due to enzymatic degradation.

Nov 11, 1975 · The crude product was dissolved in acetone and purified by filtering through charcoal. After concentration of the filtrate, the product, in the form of white crystals, was recovered in a 60 percent yield. Additional small amounts were recovered in the filtrate; and the final filtrate contained a dark brown, viscous tar as the residue.Hawach Scientific Co., Ltd Profile - Environmental ExpertHawach Scientific Co., Ltd BIO-44 filter paper is a star product equivalent to Whatmans Grade 44 with more competitive price, which has a high retention rate and slow flow rate (3m). BIO 44 filter paper has lower ash than other filter papers in this series. The efficiency of collecting small particles is slightly lower than that of BIO 42, but the flow rate is faster.Legal Chemistry, by A. Naquet, a Project Gutenberg eBookThe materials supposed to contain arsenic are boiled in water which has been rendered strongly alkaline by the addition of pure potassa. The fluid is then filtered, an excess of hydrochloric acid added, and a current of sulphuretted hydrogen conducted through it. If arsenic be present in the suspected fluid, it is soon precipitated as a yellow sulphide.
