US Classification:

210656, 210659, 210660, 210661, 210680, 554191, 554193

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:

A battery electrolyte solution contains from 0. 01 to 80% by weight of an aromatic phosphorus compound. The aromatic phosphorus compound provides increased thermal stability for the electrolyte, helping to reduce thermal degradation, thermal runaway reactions and the possibility of burning. The aromatic phosphorus compound has little adverse impact on the electrical properties of the battery, and in some cases actually improves battery performance.

Appl. No.:

6/922920

Inventors:

Thomas D. Gregory - Midland MI

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

H01M 618

US Classification:

429192

Abstract:

An anionically conductive polymer electrolyte, solid at ambient temperature, containing a salt of the formula: (R). sub. 3 CMX. sub. n, wherein M is selected from the group consisting of at least one of boron, phosphorus, antimony, and arsenic, wherein X is halogen, n is 4 or 6, and R is aryl of 6-18 carbon atoms, alkyl of 1-8 carbon atoms, or alkaryl of 7-26 carbon atoms. The polymer is derived from at least one monomer having at least one heteroatom in the monomer unit selected from oxygen, nitrogen, sulfur, and phosphorus. The electrolyte can be prepared by mixing the polymer and the salt together in the presence of a diluent or solvent and removing the diluent or solvent or by polymerizing a salt and monomer mixture utilizing a metal or a Lewis acid catalyst.

International Classification:

C25B 114
C25B 304

US Classification:

204 585

Abstract:

Included is an invention, which in one aspect, is a process for preparing a product of an alkaline earth metal compound having at least one BVB-heteromoeity and by-product of an alkali metal substance comprising operating an electrochemical cell, said cell having (1) a sacrificial alkaline earth metal anode, (2) a liquid electrolyte, which contains a solvent that is generally inert and a solute that has at least a residual alkali metal moiety and an incorporatable BVB-heteromoiety therein, and (3) an alkali metal substance segregative cathode, under conditions whereby said product and by-product are prepared. Provided, among other products, are alkaline earth metal organoborates. For example, magnesium triethylpyrrolylborate can be prepared by employing a magnesium anode, a solution of lithium triethylpyrrolylborate in tetrahydrofuran and a cupric oxide and carbon containing cathode. Intercalating cathodes can provide electrical current output.

C08G 6942

US Classification:

528185

Abstract:

The invention is a condensation polymerization reaction in which functionally terminated polybenzazole ligomers are reacted in a solvent acid at a temperature of at least 150. degree. C. and a shear of at least about 10 sec. sup. -1 under conditions so that the desired molecular weight is reached in no more than about 4 hours. The oligomers may be, for example, derived from the reaction of 4,6-diaminoresorcinol bis(hydrochloride) and terephthalic acid. The concentration of oligomers is high enough so that the reaction mixture contains liquid crystalline domains.
