    摘要： This invention relates to a method of making an olefin from a dialkyl ether comprising (a) introducing an ether having a formula CxH2x+1CyH2y+1 into a thermal or catalytic cracking unit processing a hydrocarbon feedstock; and (b) decomposing at least a portion of the ether to form an olefin having a formula CxH2x and/or CyH2y and an alcohol having a formula CxH2x+1 and/or CyH2y+1OH, wherein x and y independently range from about 1 to about 30. This invention also relates to a method of reducing coking in a thermal or catalytic cracking unit comprising (a) introducing an ether, having a formula CxH2x+1OCyH2y+1, into the cracking unit processing a hydrocarbon feedstock in an amount effective to reduce coke formation relative to processing the hydrocarbon feedstock in the absence of the ether, wherein x and y independently range from about 1 to about 30.

    摘要： The present invention provides for amino-crosslinkable coating formulations based on a mixture of a di- or polyhydroxy functional polymeric component selected from the group consisting of diesters, polyesters, alkyd polymers, acrylic polymers and polycarbonate polymers, a crosslinking agent such as a methylol (alkoxymethyl) amino crosslinking agent, and a reactive additive which is the ester reaction product of a phenol carboxylic acid, preferably para-hydroxybenzoic acid, and an epoxy compound selected from glycidyl ethers, glycidyl esters, linear epoxies and aromatic epoxies. The crosslinkable compositions of this invention may be used to prepare curable coating and paint formulations, and also may contain other ingredients such as a crosslinking catalyst, fillers, pigments and the like. When cured, the coatings of this invention exhibit improved physical and chemical properties when compared with cured coatings which do not contain the ester reaction product additive.
