	abstract = {Recently, we discovered that water-soluble tertiary hydroxyalkyl phosphines and quaternary hydroxymethyl phosphonium salts were capable of providing a bleaching effect similar to or higher than that achievable with hydrosulphite on mechanical pulps over a wide range of pH, consistency and temperature. Now, we have found that mechanical pulps bleached with these phosphorus (P) compounds are more stable than those bleached with hydrosulphite, not only when exposed to heat and moisture, but also during ambient dark storage. One of the P compounds, tris(hydroxypropyl)phosphine (THPP), P(CH2CH2CH2OH)(3), is also effective in providing additional brightness gains to, and in improving the light stability of papers made from peroxide-bleached mechanical pulps.},

	abstract = {Recently we discovered that simple, water-soluble phosphorus compounds such as tris(hydroxymethyl)phosphine, P(CH2OH)(3) (THP), were effective bleaching agents for mechanical pulps over a wide range of consistency, pH and temperature. Now, we have found a bisphoslethine derivative of THP, 1,2-bis[bis(hydroxymethyl)phosphino]ethane, (HOCH2)(2)PCH2CH2P(CH2OH)(2)(BBHPE),to be even more effective than THP. This derivative pable of providing an ISO brightness gain of 13.0 and 15.2 points to spruce and pine thermomechanical pulps (TMP), respectively, compared to a maximum ISO brightness gain of similar to 10.0 points achievable with THP or sodium hydrosulphite. BBHPE is particularly useful as a bleaching agent for pulps that have a poor bleach response to sodium hydrosulphite. It also shows promise as a complementary bleaching agent to alkaline hydrogen peroxide. The bisphosphonium sulphate [(HOCH2)(3)pCH(2)CH(2)P(CH2OH)(3)]SO4 has also been synthesized and shown to be nearly as effective as BBHPE for the bleaching of spruce TMP and peroxide-bleached spruce TMP.},
