Substances extractable by water at room temperature from weathered fusinitic brown coal have been investigated. Thirty-four aromatic carboxylic acids, mainly polycyclic keto and keto-hydroxy carboxylic acids, and also plamitic acid have been identified. The presence of labile ..beta..-keto carboxylic acids, of small amounts of C/sub 14/-C/sub 33/ n-paraffins, and of amino acids has been established.
