Abstract: Textile fabrics have been bleached with aqueous solutions of hydrogen peroxide for many years. Since hydrogen peroxide is quite unstable under bleaching conditions, stabilizers have been necessary and silicate of soda, commonly called water glass, is the stabilizer commonly used in the industry. Water glass has a number of disadvantages when used in commercial bleaching of textiles. This invention provides new processes for bleaching textile fabrics with aqueous solutions of hydrogen peroxide containing sodium orthosilicate in combination with a magnesium ion-polyphosphate ion stabilizer and new compositions of matter comprising aqueous solutions of hydrogen peroxide containing an effective amount of sodium orthosilicate and magnesium-polyphosphate stabilizer.

Abstract: Thiophene is continuously produced by reacting normal butane or a normal butene and hydrogen sulfide at elevated temperatures over a dehydrogenation catalyst, said reaction being conducted in the presence of sulfur vapor introduced in an amount to maintain the elevated reaction temperature and to overcome the heat loss caused by the endothermic reaction between the C.sub.4 hydrocarbon and hydrogen sulfide.The mole ratio of hydrogen sulfide to C.sub.4 hydrocarbon must be maintained within the range of 15 to 20 moles of hydrogen sulfide per mole of n-butane or n-butene. Conversions may vary from 60 to 20% per pass depending on catalyst activity. This requires that unreacted C.sub.4 hydrocarbon and hydrogen sulfide be recirculated. Carbon disulfide is a by-product of the reaction along with nominal amounts of other materials.

Abstract: Sodium tetraborate based carrier coatings for wire drawing are prepared by dispersing a water insoluble fatty acid metal salt in a sodium tetraborate coating bath. The carrier coatings on rod are made resistant to atmospheric moisture by heating at an elevated temperature.Carrier coatings on wire rod provide a vehicle to pick up the wire drawing lubricant in the soap box and carry the lubricant into the die. Since the coated wire rod is often stored for long periods between coating and drawing it is susceptible to corrosion from atmospheric moisture.BACKGROUND OF THE INVENTIONThe two principal carrier coatings for drawing rod are based on borax or lime. Lime carrier coatings have two main disadvantages. First, it is difficult to apply a lime coating since the lime floats in the water. Secondly, the lime coating flakes off lime particles in the work area causing disagreeable breathing conditions and dirty work areas.
