Add sulfuric acid to the mixture of benzoic and methanol‚ heat up the mixture to 65 oC. Transfer the mixture to the separatory funnel and add ether‚ sodium bicarbonate and saturated sodium chloride-brine solution‚ drain the bottom layer each time and remain ether layer. Decant the solution with calcium chloride‚then evaporate the ether by steam bath and cool down. The product is methyl benzoate. Pour methyl benzoate into cool concentrated sulfuric acid and keep the temperature below 10oC. Add concentrated

Calcium hypochlorite is a chemical compound with formula Ca(ClO)2. It is widely used for water treatment and as a bleaching agent. This chemical is considered to be relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Preparation It is manufactured by the calcium process: ~\mathrm{2Cl_2 + 2Ca(OH)_2\longrightarrow \ Ca(OCl)_2 + CaCl_2 + 2H_2O}. "Bleaching powder" is a mixture of calcium hypochlorite (Ca(OCl)2) and the basic chloride CaCl2‚ H2O with
