  • Patent number: 4120840
    Abstract: A method for the stabilization of both water-in-oil emulsions and solutions of poly trimethylamino methylol acrylamide is disclosed. The process consists of adding to the water-in-oil emulsion or solution containing the polymer from 10-50 mole percent of orthophosphorus acid based on the weight of the polymer. Water-in-oil emulsions of polymer are then stabilized by heating the emulsion for a period of time to obtain a stabilized emulsion of a water-soluble quaternary salt of poly trimethylamino methylol acrylamide. Solutions of poly trimethylamino methylol acrylamide need not be heated and are stablized by the addition of the orthophosphorus acid and mixing.

  • Patent number: 4105540
    Abstract: Phosphate and phosphite mono and diesters in small amounts function as antifoulant additives in ethylene cracking furnaces which are subjected to elevated temperatures from about 500.degree. - 1700.degree. F. These furnaces produce material that deposits and accumulates upon furnace surfaces including furnace coils and transfer line exchangers. The present antifoulant additives inhibit and suppress fouling and also help clean up previously fouled furnace surfaces.

  • Patent number: 4102821
    Abstract: A method for preparing a hydrotreating catalyst having a controlled pore distribution is disclosed. The method requires adding to the alumina prior to forming from 0.1 to 15% by weight of a water soluble polycarboxylic acid having from 2 - 22 carbon atoms. The resulting formed alumina support after being calcined has a pore volume distribution such that most of the pore volume in pores greater than 200 A in diameter as measured by Mercury penetration porosimitry is substantially eliminated. The pore volume as measured by nitrogen adsorption in the range of between 100 A and 1200 A is reduced. The polycarboxylic acid may be added to the catalyst carrier prior to forming in different ways such as by dissolving the catalytically active metals with the water soluble polycarboxylic acid and then impregnating hydrothermally or by pore volume or by adding a water soluble polycarboxylic acid salt to the hydrous or xero gel after precipitation.
