Grade Specifications

Maximum level of impurities: Evaporation residue 0.003%, Cl 5ppm, PO4 0.001%, SO4 5ppm, Heavy Metals (as Pb) 2ppm, Fe 5ppm, Substances reducing permanganate P.T.

Applications

It is most suited for the conversion of cellulose into cellulose acetate and in the manufacture of aspirin. It acts as a wood preservative and solvent in examination of wood fat, fatty and volatile oils and detection of rosins. In many organic reactions it acts as a dehydrating agent. Also used in the production of isoamyl alcohol and 2-methyl furan.

Notes

Reacts with water to form acetic acid with the liberation of heat violently.
