Title: Improvements in thread made from a polyurethane
IPC: C08G18/10
Filed: 1957-09-27
Abstract: An elastomeric thread comprises a surface layer and an inner core surrounded by said surface layer, the surface layer comprising a cured polyurethane elastomer which is the reaction product of a polymer having terminal alcoholic hydroxyl groups selected from polyesters and polyethers, a molar excess of an aromatic di-isocyanate and an aliphatic primary diamine, the inner core comprising a cured polyurethane elastomer which is a reaction product of said polymer and said di-isocyanate and water, the diamine and the water being the curing agents for the surface layer and inner core respectively.  Such a thread is obtained by extruding a stream of a liquid polyurethane prepolymer which is a reaction product of a polymer having terminal hydroxyl groups selected from polyesters and polyethers with an excess of an aromatic diisocyanate over the amount required to react with all the hydroxyl groups of the polyester or polyether, passing the extruded stream into a bath containing a primary aliphatic diamine to effect an initial setting of the extruded material, and thereafter curing the interior of the thread by the action of water under pressure.  Polyethers can be used in conjunction with the polyester as an added reagent or as part of the polyester molecule (e.g. in polydiethylene glycol adipate).  As di-isocyanates there are specified m- and p-phenylene, toluene, p,p-diphenyl, 1,5-naphthalene, p,p-diphenylmethane and phenylethane di-isocyanates.  The diamine is suitably used in 0,5 to 20% aqueous solution at 100 DEG  to 200 DEG  F.  Specified diamines are ethylene diamine 1,2- or 1,3-diaminopropane, hexamethylene diamine, 1,4-diaminocyclohexane, 3,31-diaminodipropyl ether and diaminodibutyl sulphide. Preferably there is also included in the setting bath a small amount of wetting agent.  The finished threads may vary from round to nearly flat in section.  In an example a hydroxypolyester from ethylene and propylene glycols and adipic acid is reacted with excess p,p-diphenyl methane di-isocyanate.  The liquid prepolymer obtained is heated to 250 DEG  F and passed through a spinneret into 5% ethylene diamine solution at 110 DEG  to 160 DEG  F.  The thread is conveyed through this solution, sprayed with ammonia to remove tackiness, wound on to a reel and treated with hot water under pressure.

Title: Purification process for hydrocarbons
IPC: C07C7/10
Filed: 1953-11-10
Abstract: Hydrocarbon material contaminated with minor amounts of non-hydrocarbonaceous impurities such as sulphur-containing substances are purified by contacting them with molten urea and recovering a hydrocarbon product substantially free from said contaminants.  The purified hydrocarbons may be contacted with carbon monoxide and hydrogen in the presence of a cobalt carbonylation catalyst to produce aldehydes which may be hydrogenated to produce alcohols.  The initial hydrocarbons may be straight or branched chain olefines such as diolefines, propylene, butylene, styrene, and di- and tri-isobutylene.  The catalyst for the production of the aldehyde may be a slurry of cobalt or its carbonyl, or an oil soluble salt such as that derived from oleic, stearic or naphthenic acid; and for the second stage it may be nickel, tungsten or molybdenum or an oxide or sulphide of these metals.  The preferred alcohols are octyl and nonyl alcohols which may be used to prepare light coloured esters from phthalic, maleic or adipic acids and phthalic and maleic acid anhydrides, for use as plasticizers.  The sulphur content is reduced to the order of 5 parts per million.  In an example the hydrocarbon stream is passed through a tower in a 1:1 ratio with urea at a temperature of 270-320 DEG  F.
