Patent number: 8119846Abstract: Described is a process for separating an organic phase comprising mainly propyl bromide from a crude reaction mixture formed by free-radical catalyzed hydrobromination of propylene with hydrogen bromide. The process comprises (A) feeding cold water into an upper or mid-portion of a packed column; (B) concurrently feeding the crude reaction mixture into an upper portion and/or mid-portion of the column so that the water contacts the crude reaction mixture; to form a mixture of (i) an acidic aqueous phase comprising aqueous hydrogen bromide and (ii) an organic phase comprising propyl bromide; (C) withdrawing the resultant phases from said column, at a rate comparable to the feeds being made into the column; and (D) separating the phases to form an upper acidic aqueous phase comprising aqueous hydrogen bromide superposed on a lower liquid organic phase comprising propyl bromide, and separating these upper and lower phases from each other.Type: GrantFiled: June 1, 2007Date of Patent: February 21, 2012Assignee: Albemarle CorporationInventors: Alvin E.

Patent number: 5290945Abstract: This invention relates to a process for preparing a white bisimide product which principally contains N,N'-alkylene-bis(tetrabromophthalimide) or N,N'-bis(tetrabromophthalimide). The process features: providing, in a reaction vessel, a solution containing tetrabromophthalic anhydride and a solvent which contains at least about 15 weight percent of a mono-, di- or tri- carboxylic acid having a dissociation constant not higher than 1.0.times.10.sup.-3 at 25.degree. C.; forming a reaction mass by adding to the solution a diamine or a diamine salt formed by the partial or total diamine neutralization of a mono-, di- or tri- carboxylic acid having a dissociation constant not higher than 1.0.times.10.sup.-3 at 25.degree. C.Type: GrantFiled: August 11, 1992Date of Patent: March 1, 1994Assignee: Ethyl CorporationInventors: Ranjit K. Roy, Ali M. Dadgar, Donald O. Hutchinson, Keith G. Anderson

Patent number: 5144053Abstract: Linear 1-olefins are prepared from internal olefins by (i) reacting them in the presence of an isomerization catalyst and a tri-lower alkyl aluminum so as to cause internal olefin to isomerize to 1-olefins which displace the lower alkyl groups to form a trialkyl aluminum compound in which at least one of the alkyl groups is a linear alkyl derived from the 1-olefin, and, thereafter, (ii) reacting the trialkyl aluminum compound with a 1-olefin so as to displace the linear alkyl from the trialkyl aluminum compound, thereby forming a linear 1-olefin product which is substantially free of internal olefins.Type: GrantFiled: December 9, 1991Date of Patent: September 1, 1992Assignee: Ethyl CorporationInventors: Robert H. Allen, Keith G. Anderson, Steven P. Diefenbach, Ronny W. Lin, Larry H. Nemec, Andrew D. Overstreet, Gene C. Robinson

Patent number: 4992557Abstract: In a first embodiment this invention relates to a process for preparing a white product which principally contains a bisimide. The process comprises: providing tetrabromophthalic anhydride and a solvent in a reaction vessel; forming, at a temperature within the range of from about 140.degree. C. to about 200.degree. C., a reaction mass by adding a diamine, a diamine salt or a mixture thereof to the solution, the formation of the reaction mass resulting in the production of a bisimide precipitate which becomes a component of the reaction mass; terminating the addition of the diamine when the molar ratio of the tetrabromophthalic anhydride initially present in the solution to the diamine or diamine salt added is substantially stoichiometric; cooking the bisimide precipitate to increase the average sphericity of the particles making up the bisimide precipitate; and recovering from the reaction mass, as the bisimide product, the cooked precipitate.Type: GrantFiled: March 5, 1990Date of Patent: February 12, 1991Assignee: Ethyl CorporationInventors: Donald O.
