Procedure. Dissolve the sample in distilled water and take an aliquot which should contain not more than 50 pg of phenolic compound. Use the aqueous ammonia to adjust the pH of the solution to 9.7-10.3 (pH meter), and then dilute to 500 mL with distilled water. Transfer the solution to a large separatory funnel, add 1.0 mL of solution A followed by 10 mL of solution B. Shake well to ensure thorough mixing, and then carry out three extractions with successive portions of 15 mL, 10 mL and 5 mL of chloroform (trichloromethane). Combine the chloroform extracts and make up the volume to 30 mL. Measure the absorbance of the extract against a blank of chloroform at a wavelength of 460 nm (blue filter), using 1 cm cells. The colour may tend to fade after 10 minutes and so speed is essential. 

Chloroform Chloroform (trichloromethane, CHC13) is a nonflammable organic liquid with low miscibility with water (approximately 7.5 g/L at 25°C). It shows carcinogenic effects in animal studies and should be avoided when another solvent would do as well. Vapors should not be inhaled, and contact with the skin should be avoided.

If chloroform (trichloromethane) exhibits an infrared peak at 3 018 cm-1 due to the C-H stretching vibration, calculate the wavenumber of the absorption band corresponding to the C D stretching vibration in deuterochloroform (experimental value 2253 cm-1). 

Chloroform (trichloromethane). [CAS 67-66-3], Although chloroform can be prepared by various means it is almost exclusively produced by the chlorination of methane. It can be oxidized to phosgene, substituted with various halogens, nitrated to chloropicnn (CljCNOi). hydrolyzed lo formic O...

Chloroform (trichloromethane, CHClj). Chloroform was first used as an anaesthetic in 1847 and its narcotic effects on the central nervous are well documented (ref. 4la). It has important applications as an intermediate in the chemical synthesis of a large number of industrial chemicals chlorofluorocarbons, dyes, drugs and pesticides. Its powerful solvent properties and low boiling point (6l°C) have made it a favorite for extractive and purification operations in preparing antibiotics, alkaloids, flavors and vitamins.

Treatment of a phenol with chloroform (trichloromethane) in the presence of hydroxide ion results in the synthesis of a 2-hydroxybenzalde-hyde through C-formylation. Dichlorocarbene, CCl2, is generated by the action of base on chloroform and this highly reactive electrophile then attacks the phenoxide. The mechanism of the Reimer-Tiemann reaction, is given in Scheme 4.12.
