Synthesis of Chloroform -------------------------------------------------------------------------------- With Calcium Hypochlorite and Acetone When chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone

experiment‚ the hood in the lab was used. The curds were placed in a 100 mL beaker and extracted using 30 mL of ethyl acetate. The curds were crushed with a stirring rod. This extraction was then gravity filtered through a funnel fitted with the filter paper. A rubber policeman was used to scrape the beaker to get as much casein as possible. This casein was then put aside in the hood safely. Boiling chips were put into an Erlenmeyer flask along with the filtrate collected. This flask was then put inside
