Method for producing 1-octene from butadiene by dimerizing and alkoxylating butadiene in the presence of one or more alkoxy substituted phosphine ligands under alkoxydimerization conditions with an alkoxydimerization catalyst, the alkoxydimerization conditions being effective to produce an alkoxydimerization product with one or more alkoxy substituted octadienes comprising primarily 1-alkoxy substituted octadiene; hydrogenating the alkoxydimerization product under hydrogenation conditions effective to produce a hydrogenation product which is primarily 1-alkoxy substituted octane; eliminating the alkoxy group from the hydrogenation product under elimination conditions effective to produce an elimination product which is primarily 1-octene and a first alkanol having from about 1 to about 3 carbon atoms; and separating the 1-octene from said elimination product.

Process for producing 1-octene from butadiene

A detergent composition having cold water solubility and exhibiting high calcium tolerance can be produced from biodegradable branched ether derivative compositions derived from a branched ether primary alcohol represented by the formula: wherein Rrepresents hydrogen or a hydrocarbyl radical having from 1 to 3 carbon atoms, Rrepresents a hydrocarbyl radical having from 1 to 7 carbon atoms, x is a number ranging from 0 to 16, preferably from 3 to 13, wherein the total number of carbon atoms in the alcohol ranges from 9 to 24.

Branched primary alcohol compositions and derivatives thereof

Novel detergent molecules and methods for producing such detergent molecules by dimerizing and alkoxylating butadiene with one or more reactant alkanol selected from the group consisting of a primary alkanol and an &#x3b1;, &#x3c9;-diol, hydrogenating the alkoxydimerization product to produce a hydrogenation product selected from the group consisting of primarily 1-alkoxy substituted 2-octene and primarily 1-hydroxy-alkoxyoctane, and hydroxylating the 1-alkoxy substituted 2-octene to produce primarily 1-hydroxy-9-alkoxy nonanes.

Process for producing detergent molecules comprising an ether linkage from butadiene

A detergent composition having cold water solubility and exhibiting high calcium tolerance can be produced from biodegradable branched ether derivative compositions derived from a branched ether primary alcohol represented by the formula:wherein Rrepresents hydrogen or a hydrocarbyl radical having from 1 to 3 carbon atoms, Rrepresents a hydrocarbyl radical having from 1 to 7 carbon atoms, x is a number ranging from 0 to 16, preferably from 3 to 13, wherein the total number of carbon atoms in the alcohol ranges from 9 to 24.

A method of ensuring the production of efficient lanthanum phosphate catalysts (LAPO's) and rare earth phosphate catalysts (REPO's), and methods of alkoxylation using said efficient catalysts.

Preparation of efficient REPO and LAPO catalysts

A process to prepare an improved fluid rare earth phosphate catalyst composition useful in preparing alkylene oxide adducts of organic compounds having active hydrogen atoms is provided. The catalyst is prepared by dissolving a rare earth salt in a C -C active hydrogen containing organic compound and then adding phosphoric acid to the organic compound rare earth mixture.

Process of preparing a fluid rare earth alkoxylation catalyst

The present invention relates to reaction products formed from maleic anhydride and amino carboxylic acids. The reaction products are particularly useful for grafting polyolefins to increase their polarity and therefore enhance their physical properties.

Preformed multi-acid adducts useful for grafting polyolefin polymers

A grafted polyolefin polymers having high polarity produced by grafting bi-functional N-substituted diacids to maleated or other functional group grafted polyolefin. The new polymers exhibit improved water miscibility, compatability and good adhesion to polar materials such as nylon, polyester, glass, and metal substrates.

Polyfunctional polyolefins

A process to produce terephthalic acid is provided, the process including the steps of: providing a feed stream comprising a dialkyl substituted aromatic and in an organic acid solvent: contacting the feed stream with an oxidant, the oxidant containing at least 50% by volume oxygen and at an oxygen partial pressure of at least 1 psia, at a temperature between about 80.degree. C. and about 130.degree. C., in the presence of a catalyst system comprising zirconium and cobalt, wherein the contacting is done in a stirred tank reactor; removing from the stirred tank reactor a vapor stream comprising the organic acid, water vapor and unreacted oxidant; condensing at least a portion of the organic acid and water from the vapor stream; separating at least a portion of the water from the organic acid back to the stirred tank reactor; returning at least a portion of the condensed organic acid back to the stirred tank reactor; continuously recovering from the stirred tank reactor a product comprising a diacid substituted aromatic; isolating solid crystals of diacid substituted aromatic from the reactor product; and recovering from the solid crystals a diacid substituted aromatic having a purity of preferably at least 97% by weight.

Method to produce aromatic dicarboxylic acids using cobalt and zirconium

The present invention is directed to the use of cyclic amide alkoxylate compounds as additives in fuel compositions having a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of one or more cyclic amide alkoxylate compounds of the formula: ##STR1## wherein x is from 2 to 20 and y is from 1 to 50. R.sub.1 and R.sub.2 are independently hydrogen or hydrocarbyl of 1 to 100 carbon atoms. R.sub.3 is hydrocarbyl of 1 to 100 carbon atoms and R.sub.4 is independently hydrocarbyl of 2 to 100 carbon atoms. R.sub.5 is hydrogen, hydrocarbyl of 1 to 100 carbon atoms or acyl of 1 to 20 carbon atoms. The invention is also directed to the use of these cyclic amide alkoxylate compounds for decreasing intake valve deposits, controlling octane requirement increases and reducing octane requirement. The invention is further directed to novel cyclic amide alkoxylate compounds.
