This report deals with the preparation of lignin samples by treating soda lignin from beech-wood and cryptomeria with acid chlorides, such as phosphorus oxychloride, sulfuryl chloride and thionyl chloride, and this is oxidatively de composed with mercury oxide or copper ocide to obtain 2, 5-dihydroxybenzal-deyde and 2, 5-dihydroxybenxoic aid from soda lignin of beech-wood, and 3, 4-dihydroxybenzaldehyde and 3, 4-dihydroxybenzoic acid from soda lignin of cryptomeria.
