2. Using o-chlorobenzaldehyde and alkali metal salts of thioglycolic acid as raw materials Kokai et al. (JP 05194484) used o-chlorobenzaldehyde and alkali metal salts of thioglycolic acid as raw materials to first condense and form the intermediate 2-formylphenylthioacetate.

At higher saturations water droplets condense, a large crater forms below, and freezing proceeds undetectably beneath the droplet. Our approach is a general framework that naturally models freezing close to three phase coexistence and provides a first principle theory of ice growth and melting which...
