METHOD FOR PRODUCTION OF LIGNIN |
摘要 |
A method for the preparation of lignin, characterized in that an acid is added to an alkaline alcoholic solution of lignin and the precipitated lignin is separated, and, optionally, from the filtrate alcohol is removed in order to get further lignin; as well as a method for the preparation of a concentrated alkaline, alcoholic solution of lignin by membrane filtration; the use of the lignin thus prepared; and the isolation of hydroxy cinnamic acids from the solution, from which the lignin has been separated. |
