Abstract: Alkyl ether amines are used as foam control compounds in foodstuff processing. The alkyl ether amines can be used at various stages during industrial processing of vegetables, fruits, and plants, such as potatoes and beets. The alkyl ether amines are generally of lower molecular weights and therefore easily transported to the foam layer to break the foam structure. Further, the alkyl ether amines are water soluble and therefore can be readily removed from the food processing system.

Abstract: A prepolymer comprising an acid group is made by a process comprising the step of contacting: (i) a di-isocyanate, (ii) a polyol containing an acid group, and (iii) a polyol without an acid group, the contacting conducted under reaction conditions and in a solvent consisting essentially of: (A) a first component consisting essentially of at least one glycol ether ketone, and (B) optionally, a second component consisting of at least one aprotic glycol ether. The prepolymer is useful in the preparation of water-based polyurethane dispersions.

In one aspect, an azeotropic blend or a pseudoazeotropic blend consists essentially of octamethyltrisiloxane and a second component selected from the following: amyl acetate, 2-propoxyethanol, 1-methoxy-2-propylacetate, and 1-propoxy-2-propanol.

Abstract: Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 5,000 centipoise at 25 #C and having a glass transition temperature of at most 20 #C. The tackifier is pre-blended with certain monols to form a lower-viscosity blend that is combined with one or more other polyols and a polyisocyanate to form a reaction mixture for producing a polyurethane foam.

Abstract: A prepolymer comprising acid functionality is made by a process comprising the step of contacting: (i) a di-isocyanate, (ii) a polyol containing an acid group, (iii) a polyol without an acid group, and (iv) a metal salt catalyst, the contacting conducted under reaction conditions and in a solvent consisting essentially of: (A) a dialkyl amide, and (B) optionally, an aprotic glycol ether. The prepolymer is useful in the preparation of water-based polyurethane dispersions, and certain of the solvent blends consisting essentially of a dialkyl amide and an optional aprotic glycol ether are azeotropic or pseudo-azeotropic.

Abstract: Oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. A bitumen recovery process may be used to extract bitumen from oil sands. Specifically, the bitumen recover process involves a step of treating oil sands with a propylene oxide capped glycol ether described by the structure: RO—(C2H4O)n—CH2CH(CH3)OH wherein R is a linear, branched, or cyclic alkyl, phenyl, alkyl phenyl group and n is 1 to 10.
