摘要： The invention provides branched hydrophobes for the production of surfactants with improved properties over linear hydrophobes. The invention also provides branched C10-12 enals and aldehydes. The invention additionally provides branched C10-12 enals and aldehydes that are oxidized to branched fatty acids or hydrogenated to branched fatty alcohols and further derivatized to surfactants, through ethoxylation or esterification and other or subsequent reactions. The enals and aldehydes are useful in making branched trialkylamine intermediates useful in making certain surfactants, including amphoteric, cationic and nonionic surfactants. The surfactants which can be produced from the trialkylamine intermediates include the quaternary ammonium compounds of the invention. The quaternary ammonium compounds of the invention are also useful in making the branched enals and/or aldehydes useful in the invention.

摘要： The oxidation of isobutyraldehyde produces isobutyric acid and byproducts, such as isopropyl formate. A process of reducing the isopropyl formate byproduct and other byproducts in the oxidation of isobutyraldehyde is described. The process uses a carbonyl compound, such as acetone, to reduce byproduct levels in the resulting product. Process for use of static mixers in oxidation reactions of aldehydes are also provided.

摘要： The oxidation of isobutyraldehyde produces isobutyric acid and byproducts, such as isopropyl formate. A method of reducing the isopropyl formate byproduct in the oxidation of isobutyraldehyde is described. The method uses a co-solvent, such as acetone, to the isobutyraldehyde feed to increase both the selectivity of the reaction to isobutyric acid and the production rate of isobutyric acid so that the isopropyl formate byproduct is significantly reduced.

摘要： An efficient process useful for the self-condensation of aliphatic aldehydes is provided, catalyzed by dialkylammonium carboxylate salts. In particular, the invention provides a facile method for the preparation of 2-ethyl hexenal via the self-condensation of butyraldehyde using various dialkylammonium carboxylates, e.g., diisopropylammonium acetate or dimethylammonium acetate, as catalyst. Additionally, residual nitrogen arising from the catalyst can be reduced to −100 ppm levels in the product via a simple washing procedure. The invention provides a process for preparing alkenals under conditions which limit the formation of undesired impurities and high-boiling oligomeric substances.

摘要： Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.
