A literature survey is presented pioneering the use of hydrotropic solvents in producing wood pulps. The strength characteristics of three hydrotropic pulps (54, 77, and 85% yield) are investigated and compared to a commercial NSSC pulp (70% yield).
The experimental results indicate that the strength characteristics of the hydrotropic pulps increase as the yield decreases, however all pulps were lower in strength characteristics than the NSSC. It appears that the cooking liquor would have to be kept from becoming acid if a higher strength pulp is to be produced.
