Starch sulfomaleate half-esters, a method for their preparation and their use to prepare starch disulfosuccinate half-esters |
| abstract |
Novel starch sulfomaleate half-esters are prepared by reacting a starch base or a modified starch containing anionic, cationic, and/or nonionic substituent groups with about 0.1 to 100% by weight of sulfomaleic anhydride or its salts. The reaction is carried out at pH 5-9 and at 5 DEG -90 DEG C. for 0.5-20 hours or at pH 9-11 and at 5 DEG -30 DEG C. for about 0.5-3 hours. The starch sulfomaleates may be reacted with sulfurous acid or its acid salts (e.g. sodium bisulfite) to form the novel starch disulfosuccinate. |
