  • Patent number: 4216168
    Abstract: High purity tetrahydrocarbylammonium tetrahydridoborates are prepared under anhydrous conditions by reacting tetrahydrocarbylammonium salts with at least 8% molar excess of an alkali metal hydroxide in the presence of ethanol to produce the corresponding tetrahydrocarbylammonium hydroxides and alkali metal salts, removing the alkali metal salts and adding an alkali metal borohydride to the solution to produce the corresponding tetrahydrocarbylammonium tetrahydridoborates and alkali metal hydroxides.
    Type: Grant
    Filed: October 16, 1978
    Date of Patent: August 5, 1980
    Assignee: Allied Chemical Corporation
    Inventors: Francis E. Evans, Charles J. Lind, Martin A. Robinson
  • Patent number: 4209654
    Abstract: When saturated with boron trifluoride, certain polyhydric alcohols form adducts which catalyze reactions for which boron trifluoride is catalytic. The adduct is recovered from the reaction mixture and recycled, greatly reducing boron and fluoride values in the product and in any effluent. Examples include propylation of toluene in the presence of a recycled adduct of boron trifluoride with mannitol or sorbitol.

    Inventors: Robert E. Booth, Francis E. Evans, Richard E. Eibeck, Martin A. Robinson
  • Patent number: 4174349
    Abstract: Fluoroorganic compounds are prepared by reacting a haloorganic starting material in which at least one halo atom is replaceable with a fluorine atom by metathetical exchange, with calcium fluoride in the presence of a crown ether and an anhydrous, polar, basic organic solvent which complexes with the calcium ion and contains no --OH groups, at a temperature and for a period of time adequate to effect fluorination.
    Type: Grant
    Filed: October 30, 1978
    Date of Patent: November 13, 1979
    Assignee: Allied Chemical Corporation
    Inventors: Francis E. Evans, Morris B. Berenbaum, Richard E. Eibeck, Martin A. Robinson
  • Patent number: 4157377
    Abstract: Dry calcium fluoborate suitable for use in the manufacture of boron trifluoride is produced by reacting, in an aqueous medium, calcium fluoride, hydrofluoric acid and boric acid followed by removing water from the calcium fluoborate reaction product by purging the reaction product with a dry inert gas such as nitrogen, at a temperature between about 140.degree. to 160.degree.

  • Patent number: 4072726
    Abstract: Fluorinated esters of the formula C.sub.n H.sub.x F.sub.2n+1-x CO.sub.2 CH.sub.2 C.sub.m H.sub.y F.sub.2m+1-y such as CF.sub.3 CO.sub.2 CH.sub.2 CF.sub.3 are hydrogenated to fluorinated alcohols such as CF.sub.3 CH.sub.2 OH using a catalyst having between 50 and 100 percent, and preferably 75-95 percent CuO by weight. In the above formula n= 1 to 13, m= 1 to 13, x= 0 to 3 and y= 0 to 3. In the most preferred esters, n= m and x= y= 0. The catalyst may also contain 0-50 percent and preferably 5-25 percent by weight of a filler or binder such as a silicate salt. The reaction produces greater yields of alcohol and longer catalyst life than with chromite catalysts, and may proceed at substantially atmospheric pressures.

  • Patent number: 4072027
    Abstract: A stabilized heat exchange medium is disclosed including a fluorocarbon, an absorbant and a tribasic phosphite stabilizer. The preferred absorbants are assymetrical furan derivatives containing at least 1 oxygen with a single bond to an adjacent carbon, and is most preferably an alkyl tetrahydrofurfuryl ether. The fluorocarbon contains 1 or 2 carbons, 1 or 2 hydrogens and the remainder chlorine and fluorine. The tribasic phosphites are of the formula (R.sub.1 'O)(R.sub.2 'O)(R.sub.3 'O)P, wherein R.sub.1 ', R.sub.2 ' and R.sub.3 ' are each independently alkyl, alkenyl, phenyl, alkylene phenyl, alkylene alkylphenyl or alkylphenyl.

  • Patent number: 4012453
    Abstract: Chlorofluorinated aromatic hydrocarbons may be effectively produced by an oxychlorofluorination process by reacting a gaseous mixture of a starting material selected from an aromatic hydrocarbon and an aromatic hydrohalocarbon in which the halo atoms are selected from chloro and fluoro, or mixtures thereof, an oxygen-containing gas, a chlorinating agent selected from the group consisting of HCl and Cl.sub.2 and mixtures thereof, and HF, in the presence of a Deacon catalyst supported by a stable, inert metal salt carrier.
