  • Patent number: 4430271
    Abstract: This invention relates to a process for neutralizing detergent acid mixes containing unreacted sulfating agent such as sulfuric acid with an alkaline component such as sodium hydroxide. The neutralization process is highly exothermic and contains as a by-product large amounts of sodium sulfate. Due to the exothermic nature of the reaction it is necessary to use heat exchangers to regulate the temperature of the reaction mass following the addition of the alkaline component. When the sodium sulfate is supersaturated in the reaction mass, it has been observed that sulfate salts buildup upon the surfaces of the heat exchanger and eventually the system must be shut down to remove the buildup. This invention is therefore directed to a continuous neutralization and heat exchange process wherein the downtime required for removal of the sulfate salts from the heat exchanger surfaces is effectively eliminated.

A polyol having a branched configuration is alkoxylated with a mixture of ethylene oxide and propylene oxide and then chain extended to produce a high viscosity fluid additive which is compatible as a dispersed phase with polymer melts and does not agglomerate or separate from the melt during spinning. From about 0.1% to about 15% by weight of the additive is incorporated in polymeric structures as an antistatic agent. A useful additive composition is obtained using pentaerythritol tetrapropoxylate as the polyol and Bisphenol A diglycidyl ether as the difunctional reactant.

  • Patent number: 4170708
    Abstract: Aromatic urethanes are produced by interacting an aromatic nitro compound, an organic compound containing hydroxyl groups and carbon monoxide in the presence of a catalyst composed of elemental selenium or a selenium compound and of a promoter composed of a bicyclic amidine together with a phenolic compound or a carboxylic acid. The interaction proceeds smoothly with the aid of a small amount of the promoter, attended with secondary production of amino compounds only in small amounts. For instance, 2,4-diethyldicarbamatetoluene is obtained at a yield of 87% by interacting 2,4-dinitrotoluene, ethanol and carbon monoxide in the presence of a catalytic system composed of metallic selenium, 1,8-diazabicyclo(5,4,0)-undecene-7 and acetic acid.
