Process For Producing A High Purity Dibromoneopentyl Glycol Product
US Patent:
4913848, Apr 3, 1990
Filed:
Oct 12, 1988
Appl. No.:
7/256593
Inventors:
John Y. Lee - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond CA
International Classification:
C09K 2100, C07C 3134, C07C 6934, C07C 6952
US Classification:
252609
Abstract:
This invention relates to a process for treating a first product which contains monobromopentaerythritol, dibromoneopentyl glycol and tribromoneopentyl alcohol to yield a second product having a dibromoneopentyl glycol content, on a weight percent basis, greater than that of the first product. The process features forming a stirrable mass from the first product and a solvent system in which, at a temperature within the range of from about 0. degree. C. to about 40. degree. C. , the monobromopentaerythritol and the tribromoneopentyl alcohol are more soluble than the dibromoneopentyl glycol and in which at least 85% of the dibromoneopentyl glycol in the mass is insoluble; maintaining the reaction mass within the aforementioned temperature range to realize an insoluble portion and a solvent and solute portion; and separating the insoluble portion and the solvent and solute portion without substantial precipitation of the solute from the solvent and solute portion. The separated insoluble portion is the second product.

International Classification:
C07F 502
US Classification:
568 6
Abstract:
An alkali metal fluoride is reacted with a halomagnesium tetrakis(. sup. F aryl)borate to form an alkali metal tetrakis(. sup. F aryl)borate. The alkali metal tetrakis(. sup. F aryl)borate can be isolated, or the alkali metal cation can be replaced by an organic cation.

4738802, Apr 19, 1988
Filed:
Nov 16, 1983
Appl. No.:
6/552281
Inventors:
John Y. Lee - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond VA
International Classification:
C07C 5110, C07C 59185
US Classification:
260413
Abstract:
A process for the production of an alkyl. alpha. -keto-carboxylic acid of the general formula: ##STR1## wherein: R is a linear or branched alkyl radical having from 1 to about 20 carbon atoms which comprises reacting an alkyl halide of the formula:
RX
where R is as defined above and X represents halogen, in a liquid solvent medium, with carbon monoxide at elevated temperature and pressure in the presence of a catalytic amount of a metal carbonyl compound and an alkali metal inorganic base or an alkaline earth metal inorganic base. Optionally, small amounts of LiI and/or bis(1,2-diphenylphosphino)ethane may be present in the reaction as co-catalysts.
Clean Generation Of A Perfluoroaryl Grignard Reagent
US Patent:

Assignee:
Albemarle Corporation - Richmond VA
International Classification:
C07F 302, C07F 502
US Classification:
260665G
Abstract:
Perfluoroaryl Grignard reagents are produced from a hydrocarbyl Grignard reagent and polyhaloaromatic compounds via separate additions of different polyhaloaromatic compounds, such that the conversion of hydrocarbyl Grignard reagent to the desired perfluoroaryl Grignard reagent is essentially complete, and thus the reaction product is free or essentially free of agents that may negatively affect subsequent reactions. The perfluoroaryl Grignard reagents may be further reacted with boron trihalides in order to obtain tris(perfluoroaryl)boranes or tetrakis(perfluoroaryl)borates.
