    Abstract: A process for making mono- and dichlorinated or brominated aldehydes from aldehydes having at least 3 carbon atoms and hydrogens alpha to the carbonyl group or primary alcohols having at least 3 carbon atoms and hydrogens in the 2-position by direct bromination or chlorination by carrying out the bromination or chlorination in an inert organic solvent with bromine or chlorine and containing a catalyst complex of HX and an N,N-dialkyl or cycloalkylformamide where X is a counterion.

    Abstract: Flexible polyurethane foams are prepared by reacting a polyisocyanate with a high equivalent weight polyol. At least a portion of the high equivalent weight polyol is a polyester containing hydroxymethyl groups. The polyester is prepared in a multi-step process from animal or vegetable fats, by recovering the constitutent fatty acids, hydroformylating carbon-carbon double bonds in the fatty acids and reducing to form hydroxymethyl groups, and then forming a polyester by reaction with an initiator compound.

    Abstract: A solid bed adsorptive process for separating a seed oil into two substantially pure triglyceride fractions. The process involves contacting a seed oil, such as castor oil, preferably as a concentrate, with an adsorbent in a bed, the adsorbent having a particle size greater than about 40 microns, and thereafter contacting the adsorbent with a desorbent material, preferably under minimal flow conditions, to obtain a raffinate output stream containing predominantly a second triglyceride and an extract output stream containing predominantly a first triglyceride. Purified fatty acid triglyceride esters obtainable from castor, vernonia, and lesquerella plant oils provide renewable, non-petroleum-based sources of chemical feedstocks.

    Abstract: 2-(aryl)-benz(ox, thi, imid)azoles are prepared by reacting an aromatic aldehyde with hydroxylamine to form an aromatic aldehyde oxime, halogenating the oxime to form an aromatic hydroxamoyl halide, and then reacting this halide with certain aromatic amine compounds. The products may be nitrated and then reduced to form the corresponding diamines, which are useful in making PIBX polymers.

    Abstract: A suitably functionalized cycloaliphatic nitrile oxide can be used to convert unsaturated sites to alcohol or epoxy sites. The cycloaliphatic nitrile oxide may be useful in applications such as the preparation of polycarbonates, polyurethanes, or crosslinked polybutadiene, or poly(styrene-butadiene). The cycloaliphatic nitrile oxide is represented by the formula: ##STR1## wherein R' and each R are independently hydrogen, C.sub.1 -C.sub.12 alkyl, or halo; X and X' are independently hydrogen, halo, hydroxyl, or together with the carbon atoms to which they are attached form an epoxy group, with the proviso that at least one of X and X' is not hydrogen; and n is 1 or 2.
