Abstract: The invention relates to a process for isomerizing iodoaromatic compounds over a non-acidic zeolite catalyst in the liquid or gas phase in the presence of a source of iodine.

Abstract: A process for preparing an aromatic carboxylic ester and an alkyl iodide by carbonylating an aromatic iodide in the presence of an ether, a catalytic amount of a transition metal and a strong acid promoter.

Abstract: A hydroformylation process for preparing dialdehydes from dienes by contacting a C.sub.6 -C.sub.10 diene in a reaction zone at a temperature of from about 20.degree. C. to about 250.degree. C. and a pressure of from about 15 psig to about 800 psig with hydrogen, carbon monoxide, and a catalyst containing rhodium, the ligand having the formula ##STR1## wherein: n is 1-4;each R is independently selected from hydrogen, alkyl, alkoxy, aryloxy, aryl, aralkyl, alkaryl, alkoxyalkyl, cycloaliphatic, halogen, alkanoyl, alkanoyloxy, alkoxycarbonyl, carboxyl or cyano;each R.sub.1 and R.sub.2 is independently selected from alkyl, aryl, aralkyl, alkaryl or cycloaliphatic;each R.sub.3 and R.sub.4 is independently selected from hydrogen and the R.sub.1 substituents; andeach Y is independently selected from the elements N, P, As, Sb and Bi.

Abstract: Compositions comprising polyester or polycarbonate having reacted therein a total of from about 1.0 to about 5,000 parts by weight per million parts by weight of polyester of at least one UV absorbing compound of the formula ##STR1## wherein R is alkyl or the like, X is carbonyl or sulfonyl, R.sup.1 is hydrogen or a substituent, and Y and Z are hydrogen or substituents such as cyano or alkoxycarbonyl, with the provision that at least one of R, R.sup.1, Y, and Z is, or forms part of, or contains one or more reactive groups capable of undergoing a condensation reaction under polyester forming conditions, such that the UV absorbing compound is reacted into the polymer. The compound has a maximum light absorbance within the range of from about 320 nm to about 380 nm, which is nonextractable from the polyester and stable under the polyester processing conditions, for imparting UV screening properties to the polymer.
