Abstract
Ethers of St. John's bread seed meal are prepared by treating the seed meal with mineral acid or other acid of similar dissociation constant in the presence of an inert liquid diluent and under specified conditions which avoid and substantial hydrolysis of the meal or the formation of reducing sugars, and subsequently etherifying the treated seed meal in alkaline solution by addition of halogenated fatty acid. The acid-treatment is carried out under such conditions of time, temperature and kind of acid, its concentration and its water content (if any) that by boiling 1 gm. of the acid-treated meal in 100 ml. of water for 20 mins. and slowly cooling with vigorous stirring during a further 20 mins. the resulting solution shows a viscosity which is at least one-third lower than that of a solution prepared in the same manner with meal not subjected to the acid treatment; also, the solution must give a negative result when tested with Fehling's solution. In an example, the seed meal is suspended in methanol and concentrated hydrochloric acid added; the mixture is heated for 15-30 mins. at 50 DEG C. and then neutralized with solid caustic soda; etherification of the product is effected by slow addition thereto of a solution of caustic soda and a solution of mono-chloracetic acid in methanol. The product may be used as a thickening agent for textiles.
