Abstract

The chemical treatment of plants such as sisal, esparto grass, doum palm and sugar cane, provides for the extraction and recovery of the principal constituents, and for the recovery of the undamaged cellulose. The stages comprise (a) removal of colouring, largely chlorophyll, using a solvent at a temp. where abundant liquors may be released, i.e. slightly below its b.pt. (b) removal of waxes, oils and fats, using a light solvent at its boiling point, i.e. in the vapour phase: (c) removal of pectins, using an aq. alkaline soln. of weak concn. at b. pt. under atmospheric pressure, and (d) removal of lignin, using a medium concn. of aq. alkaline soln. at b.pt. at a pressure greater than normal i.e. over 10-15 bars. The waxes, which protect the tropical plants by limiting their transpiration, thus preventing them from drying out, are completely removed for certain high grade usage of the vegetable fibres.
