There is disclosed a low calorie fat substitute comprising a sorbitol fatty acid ester with a degree of substitution of about five fatty acid groups. Foodstuffs containing the sorbitol ester are also disclosed. Processes for preparing the sorbitol fatty acid esters are also disclosed.

Low calorie fat substitute

There is disclosed a low calorie fat substitute comprising a sorbitol fatty acid ester with a degree of substitution of about four fatty acid groups. Foodstuffs containing the sorbitol tetraester are also disclosed.

Aqueous gel-forming compositions are prepared by reacting for 1-10 hours at 50.degree.-95.degree. C., melamine, formaldehyde and a sulfurous acid salt with the optional addition of a gel-modifying agent and/or a gelling agent which is added to the composition immediately prior to use.

Aqueous sulfomethylated melamine gel-forming compositions

Hydrocarbon recovery from subterranean reservoirs that are penetrated by either injector or producer wells is enhanced by selective permeability modification of the strata of the reservoir with gel-forming phenolic compositions. The injection of the phenolic composition follows a pH sequence specific to the reservoir environment which allows emplacement of the gel-forming composition the desired distance away from the wellbore and production of a uniform gel throughout the treated hydrocarbon-bearing reservoir. The permeability of a treated subterranean reservoir can be restored by treatment of the reservoir with either aqueous hypochlorite or mineral acid.

Enhanced hydrocarbon recovery by permeability modification with phenolic

A process for the preparation of a thieno-imidazole derivative, particularly descarboxybiotin, a useful intermediate for the preparation of d-biotin, which comprises reacting a thio-substituted intermediate, for example descarboxythiobiotin, with an epoxy compound in an alkanol solvent; and a process for the preparation of said intermediate by reacting a substituted imidazothiazole alcohol with anhydrous hydrogen fluoride.

Preparation of thieno-imidazole derivatives

A series of novel water-soluble sulfonated indoxyl derivatives have been prepared, including their base salts with pharmacologically acceptable cations. These particular compounds are useful as food dyes or as cosmetic colorants. 2,2'-(1,4-phenylenedimethylidyne)-bis(2,3-dihydro-3-oxo-1H-indole-5-sulfon ic acid) represents a typical and preferred member compound. Methods for preparing these compounds are provided.

Indigoid dyes

Compositions of nitrite preserved food, emulsified preparations, breakfast cereal or food premixes and erythorbyl or ascorbyl laurate or erythorbyl caprate show substantial inhibition of potentially harmful or objectionable degradation arising from N-nitrosamine formation or oxidation.
