Patent number: 9169386Abstract: Disclosed are organic, UV resistant epoxy resins derived largely from vegetable oil. More specifically, the present invention provides a virtually non-toxic, hypoallergenic UV resistant resin that gives off substantially no VOCs or disagreeable odors. The composition comprises a vegetable oil-based polyfunctional carboxylic acid, a cycloaliphatic anhydride, and an epoxy compound either of bicyclic difunctional epoxy resin, epoxidized vegetable oil or epoxidized polymer chains. The composition further comprises a catalyst and a wetting agent. In its cured state the material is leather like and exhibits high tensile strength as well as unusually high, totally reversible elongation. In an alternative embodiment, the resin comprises a cyclic anhydride.Type: GrantFiled: October 27, 2009Date of Patent: October 27, 2015Assignee: ECO GREEN RESINS, LLCInventors: Arthur Katzakian, Craig Katzakian

Patent number: 5665783Abstract: A composition for regenerating spent weak cation exchange resin and a method of utilization including salts of .alpha.-hydroxy carboxylic acids or o-hydroxy benzoic acids. The following steps are employed in cyclically regenerating polycarboxylic acid cation exchange resins: (a) utilizing a charged or alkali metal salt of polycarboxylate acid cation resin to soften water; (b) regenerating the spent resin in one step with an active regenerant of the .alpha.-hydroxy carboxylic acids or o-hydroxy benzoic acids to produce spent regenerant; (c) precipitating the polyvalent hard ions in the spent regenerant with sodium or potassium carbonate to reform the active regenerant; (d) separating the precipitate; and (e) concentrating the dilute active regenerate solution to its approximate initial concentration and recovering of water for process rinses.Type: GrantFiled: February 8, 1996Date of Patent: September 9, 1997Assignee: EcotechInventors: Arthur Katzakian, Jr., Henry Cheung, Charles E.

Patent number: 4028234Abstract: An improved process for water demineralization involving the use of a first separate column of weakly acidic cation exchange resin, a second separate column of weakly basic anion exchange resin and a third separate column of weakly acidic cation exchange resin. The cation resin is buffered with an at least dihydroxy-substituted amine. When the saline feed is passed through the system, the cations of the feed are exchanged for the buffer, releasing buffered salts. The buffered salts when passed through the anion exchange column are split, releasing the buffer that is then deposited on the third cation resin column. The latter column is then used as the first separate column during the next demineralization cycle. Thus, the buffer is internally looped which prevents contamination of the product water and also resulting in a saving of buffer. This process allows the efficient use of weak cation and anion exchange resins in a separate, fixed-bed configuration.Type: GrantFiled: September 18, 1975Date of Patent: June 7, 1977Assignee: Aerojet-General CorporationInventors: Arthur Katzakian, Jr., David O.

Patent number: 4017429Abstract: This patent describes the catalytic promotion of the reaction of oxirane-containing compounds with carboxylic acid compounds at high, ambient, and low temperature. Specifically, this patent describes the method of reacting oxirane-containing compounds with carboxyl-containing compounds, preferably at temperatures at or around ambient, in the presence of active chromium III tricarboxylate salts which have unoccupied coordination sites. More specifically this patent describes the preparation of catalytically active chromium III-tricarboxylates from normally catalytically inactive chromium III tri-carboxylate hydrates. These compounds are powerful catalysts for the reactions of oxirane compounds with both organic carboxylic acids and cyclic primary imides.Type: GrantFiled: January 14, 1975Date of Patent: April 12, 1977Assignee: Aerojet-General CorporationInventors: Roger B.
