Trithiocarbonate boosted kraft cooking for improved yield

• The effect of adding of carbon disulphide to a kraft cook has been investigated. Among the results obtained, ail increased yield has been recorded. In sulphide-containing alkaline liquors, carbon disulphide forms trithiocarbonate ions and the effects seen in the present study are attributed to this species. The increased yield is presumably an effect of end-group stabilisation of the carbohydrates.
