Esterified propoxylated glycerine (&ldquo;EPG&rdquo;) may replace up to 100% of the partially hydrogenated vegetable oil content of an edible shortening product to produce a stable emulsion containing less trans-fatty acid content. A variety of shortenings may be produced, including those used for baking, frying, and as pan coatings (release agents). A butter-like product may be produced which exhibits spreading characteristics very similar to real butter.

Plastic and semisolid edible shortening products with reduced trans-fatty acid content

Administration of alkoxylated acyl glycerine (AAG) containing lower carboxylic acid acyl moieties to mammalian subjects results in increase of lower carboxylate concentration, particularly in the colon, and may be used to treat such disorders as simple colitis, ulcerative colitis, divertive colitis, colorectal cancer, and other diseases of the gastrointestinal tract where lower carboxylates are implicated. The AAG encourage patient compliance due to substantially no odor, even when butyric acid acyl groups are employed.

Method of treating gastrointestinal disorders, particularly colitis

Low calorie fat components which have a low solids content but a reduced tendency to exhibit the gastrointestinal side effects typically associated with liquid fat substitutes are obtainable by blending esterified propoxylated glycerin materials having a relatively high solids content at 21.degree. C. with certain liquefying agents. The liquefying agents are characterized by their compatibility with the esterified propoxylated glycerin and their partial digestibility. The low calorie fat components have improved organoleptic qualities as compared to the esterified propoxylated glycerin materials alone.

Reduced calorie fat component

Low calorie fat components which have a low solids content but a reduced tendency to exhibit the gastrointestinal side effects typically associated with liquid fat substitutes are obtainable by blending esterified propoxylated glycerin materials having a relatively high solids content at 21.degree. C. with certain liquefying agents. The liquefying agents are partially digestible triacylglycerols characterized by the incorporation of both short chain carboxylic acid residues and long chain saturated fatty acid residues. The low calorie fat components have improved organoleptic qualities as compared to the esterified propoxylated glycerin materials alone.

A tertiary amine is used to catalize the stereospecific ring-opening of chiral glycidol with o-methoxyphenol to afford high yields of enantiomerically enriched guaifenesin. The optical purity of the product may be even further enhanced by recrystallization.

Process for producing enantiomerically enriched guaifenesin

A process for the oxidative conversion of methane to higher hydrocarbons is provided wherein a mixture of methane and gaseous oxidant is contacting at reactive conditions with a reducible metal oxide containing solid contact agent, the improvement comprising periodically discontinuing methane feed to the solid contact agent so that the solid agent is maintained in a more active and highly oxidized state.

Methane conversion process

Two stage process for catalytic conversion of olefins to higher

The process of the invention comprises contacting a lower olefin contaminated with an impurity such as a diene at oligomerization conditions with either a mixture of oligomerization catalyst and at least one of a methathesis catalyst and an alkaline earth oxide, or precontacting the contaminated lower olefin with methathesis catalyst, optionally combined with alkaline earth oxide, and subsequently oligomerizing the lower olefin.

Process for producing higher hydrocarbons from lower olefins

Methane is converted into higher hydrocarbons by a process wherein a gas comprising methane and molecular oxygen is contacted at elevated temperatures with a molten salt mixture containing at least one reducible metal oxide.

Molten salt hydrocarbon conversion process using oxygen containing feed

A process for converting low molecular weight gases such as methane and natural gas to higher hydrocarbons by means of a molten salt containing a synthesizing contact agent. The gas is contacted with a molten salt containing a metal, the oxide of which is reduced when contacted with methane at a temperature in the range of 500.degree. to 1000.degree. C. to produce higher hydrocarbons and water. The reduced metal oxide/salt mixture may be regenerated to the active state by contacting the molten salt mixture with an oxygen-containing gas.

Hydrocarbon conversion process using a molten salt

A method for converting normally gaseous olefins (esp., ethylene) to normally liquid hydrocarbons wherein the olefin feed is contacted with a siliceous molecular sieve at elevated temperatures and short olefin contact times under high severity conditions favorable for substantial conversion of olefins with maximized liquids productivity. ZSM-5 type zeolites and crystalline borosilicate molecular sieves are particularly preferred catalysts.
