These may be separated from organic mixtures thus: Boil the organic matter with distilled water, spirit, and acetic acid; filter, and to the fluid passed through add acetate of lead till precipitate ceases. Filter. Acetate of morphine passes through, and meconate of lead remains.
The solution of acetate of morphine may be freed from excess of lead by hydrogen sulphide and filtered, excess of hydrogen sulphide driven off by heat, and tests applied. Put the meconate of lead with water into a beaker and pass hydrogen sulphide; sulphide of lead is formed, and meconic acid set free. Filter.
