This compound was then oxidized in order to form (3). One oxidizing agent which could be used is sodium hypochlorite (bleach) with phase transfer catalyst. This method of synthesizing the salicylaldehyde is advantageous because it has a very high yield of 88%.1 It also uses many of the techniques that undergraduate students have already learned such as vacuum filtration‚ drying over anhydrous sodium sulfate‚ and recrystallization. An alternative method in which one can synthesize chiral epoxides

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

products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios in a given volume. This reaction was exothermic so I measured the heat that was produced from the reaction. Hypothesis: The reaction with the proper mole ratio will reach the highest
