| titleOfInvention | Process for the etherification and gelatinization of starch |
| abstract | Starch etherification and gelatinisation is accomplished by (a) reacting an aqueous suspension of starch with a cross-linking agent (divinyl sulphone or an urea/formaldehyde resin) until the starch is sufficiently insoluble that it deposits after soaking (5% concentration) in 1% aqueous NaOH for 30 min. at 24 deg.C., (b9 reacting an aqueous suspension of the product with a monofunctional etherifying agent (I) with swelling the starch to an extent that it is non-filtrable, and (c) filtering the starch and heating it in either alkali if divinyl sulphone was used or acid if a urea/formaldehyde resin was used, to break the crossinks and gelatinise the starch. |
