Abstract:
The present invention relates to precursor adhesive coating compositions which optionally contain water, which are particularly suitable for being admixed with at least one supercritical fluid used as a viscosity reduction diluent and then spraying this resultant liquid mixture of supercritical fluid and precursor adhesive coating composition onto a substrate to be coated. Processes for spraying these precursor adhesive coating compositions are also disclosed.
Abstract:
Methods and apparatus are disclosed for spraying liquid compositions by airless spray techniques which avoid fishtail spray patterns and desirably obtain feathered spray patterns.
Abstract:
This invention relates to a process for making amines having a high yield weight percent of diethylenetriamine (DETA) and aminoethylethanolamine (AEEA) by condensing an amino compound in the presence of a condensation catalyst selected from a Group IVB metal oxide, a Group VIB metal-containing substance and a promoted condensation catalyst. This invention also relates to an alkyleneamines producers composition rich in DETA and AEEA.
Abstract:
This invention relates to a process for making amines having a high yield weight percent of linear triethylenetetramine (L-TETA) and aminoethylethanolamine (AEEA) by condensing an amino compound in the presence of a condensation catalyst selected from a Group IVB metal oxide, a Group VIB metal-containing substance and a promoted condensation catalyst. This invention also relates to an alkyleneamines producers composition rich in L-TETA and AEEA.
Abstract:
Crude butadiene can be used for making 1,4-diacyloxy-2-butenes by acyloxylation over palladium-containing catalyst by hydrogenating the crude butadiene sufficient to enhance at least one of catalyst activity and catalyst life for acyloxylation.
Abstract:
A process for making flexible polyurethane foam, employing a silicone surfactant composition containing 5 - 20 wt % of a defined low molecular weight silicone surfactant and 95 - 80 wt % of a defined high molecular weight silicone surfactant. Use of the claimed mixture of surfactants provides product foams having improved breathability relative to foams produced using high molecular weight silicone surfactant alone.
Abstract:
Oxidative coupling of lower alkane to higher hydrocarbon is conducted using supported catalyst comprising an activity promoting amount of at least one cobalt, nickel or rhodium compound and at least one catalytically active Group IA and Group IIA metal compound in the presence of a halogen-containing component.
Abstract:
Disclosed are methods and apparatus for spraying liquid compositions by airless spray techniques so as to obtain wider spray patterns without having to alter the construction or configuration of conventional nozzles, nozzle tips or spray guns. By means of the present disclosure, the width of a spray pattern may be changed while the spraying operation is being conducted.
Abstract:
A VANADIUM- BASED CATALYST IS TREATED WITH CERTAIN SILICON- CONTAINING COMPOUNDS AS A MEANS OF NARROWING AND EFFECTIVELY REGULATING THE MOLECULAR WEIGHT DISTRIBUTION OF THE POLYMERS PRODUCED WITH THE CATALYST.
