A method for producing borohydride by causing current to flow in an electrolytic cell between an anode and a cathode, wherein a solution of trialkoxyborohydride is in contact with the cathode.

Electrolytic method for producing borohydride

Choline base is prepared by the electrolysis of choline chloride in electrolytic cells having the anode and cathode separated by a cation exchange membrane. Color stabilization of choline base is effected through concentration control and/or the addition of a sulfite prior to electrolytic manufacture of the choline base.

Method of making and color stabilization of choline base

A process for bleaching wood pulp with sodium hydrosulfite in the presence of at least 2 weight percent of hexamethylenetetramine based upon the weight of sodium hydrosulfite.

Bleaching wood pulp with sodium hydrosulfite in the presence of

An aqueous composition for bleaching wood pulp containing sodium hydrosulfite, and at least 2 weight percent hexamethylenetetramine based upon the weight of sodium hydrosulfite, wherein the solution has a pH between about 4 and about 11. The hexamethylenetetramine prevents hydrogen sulfide formation during bleaching of the wood pulp.
