  • Patent number: 4385191
    Abstract: Drastic molecular weight degradation of a p-(polybutyl-substituted phenol occurs when it is heated above 65.degree. C. in the presence of BF.sub.3 -phenolate catalyst used in the preparation of said substituted phenol by the alkylation of phenol with a butylene polymer of 500 to 3000 molecular weight. Such molecular weight degradation can be substantially suppressed by providing 20 to 30 weight percent dissolved phenol in the mixture resulting from such catalytic alkylation reaction and then rapidly heating the mixture with such amount of dissolved phenol to a temperature of from 182.degree. C. up to 200.degree. C. at extant atmospheric pressure whereat the catalyst dissociates and liberated BF.sub.3 is stripped out by phenol vapors.

  • Patent number: 4381991
    Abstract: Sulfur oxides are removed from a gas by an absorbent comprising magnesium oxide in association with at least one free or combined rare earth metal selected from the group consisting of lanthanum, cerium, praseodymium, samarium, and dysprosium, wherein the ratio by weight of inorganic oxide or oxides to rare earth metal or metals is from about 0.1 to about 30,000. Absorbed sulfur oxides are recovered as a sulfur-containing gas comprising hydrogen sulfide by contacting the spent absorbent with a hydrocarbon in the presence of a hydrocarbon cracking catalyst at a temperature from about 375.degree. to about 900.degree. C. The absorbent can be circulated through a fluidized catalytic cracking process together with the hydrocarbon cracking catalyst to reduce sulfur oxide emissions from the regeneration zone.

  • Patent number: 4378245
    Abstract: Purification of cuprous chloride is accomplished by distillation wherein cuprous chloride is recovered as the overhead product, and substantially all of the silver chloride and other impurities present report to the bottoms. Typical impurities in copper ore leach liquors include chlorides of silver, calcium, arsenic, bismuth, iron, nickel, lead, antimony, selenium, tellurium, silicon, mercury, manganese, tin, aluminum, magnesium, chromium, cobalt, cadmium, molybdenum, zinc and titanium, most of which may be excluded in large part by crystallization of cuprous chloride. Measurable amounts of these impurities, however, report to the crystals, and silver tends to co-precipitate with the copper in major amounts. Distillation accomplishes a high degree of copper-silver separation and substantial elimination of other impurities from the copper.
