Abstract

Parsol known as 4-(1, 1-dimethylethyl)-4'-methoxydibenzoylmethane is very important in blocking and/or absorbing the full spectrum of UVA rays. It was synthesized in two steps. PTSA was successfully used as catalyst and yield as researched was good. Molar concentrations of reactants, catalyst, and solvent were varied to study their effects on progress of synthesis, quality of product. Agitation effect studied was most promising from synthesis point of view. Purification of p-tert-butyl methyl ester was carried out using column chromatography instead using Widmer's column. Catalyst soda amide was used as powder and not as suspension. The yield of Parsol was 73.9%.

Abstract

Rajgeera seed (Amaranth paniculata) is now researched as rich source of squalene, earlier source reported was shark liver oil. Squalene was obtained by extraction with SFE and conventional techniques. The Squalene was estimated in the extracted oil using various techniques like UV-Visible spectrophotometer, Iodometric titration, Fourier transform Infra-red spectrophotometer and Gas chromatography. All the analytical techniques were validated by establishing calibrated graph. Out of all these gas chromatography was found to be fast, accurate and reproducible for the estimation of squalene.
