Abstract: There is disclosed a novel process for preparing products of the reaction of elemental phosphorus and elemental sulfur under reaction conditions wherein the phosphorus and sulfur are combined in a pre-mix at temperatures below the reaction temperature. The pre-mix may contain a diluent which is preferably the product of the reaction. Phosphorus pentasulfide can be prepared by heating the pre-mix to reaction temperatures wherein lower exotherm temperatures and reduced vibration are observed. Organophosphorus and thionated products can be prepared by the reaction of elemental sulfur and elemental phosphorus together with an organic compound wherein the ratio of phosphorus and sulfur generally corresponding to P.sub.2 S.sub.5. The process obviates the need for separately preparing phosphorus pentasulfide to prepare thiohated and organophosphorus compounds.

Abstract: There is disclosed a process for preparing novel tacking agents for glass fiber insulation. The tacking agent solution is prepared by adding a condensed phosphate to an aqueous solution of aluminum orthophosphate to provide a homogeneous solution having an Al:P molar ratio of less than 1, preferably 1:3 and wherein the amount of condensed phosphate comprises from about 25 to about 75 percent of the total phosphate in the solution. The tacking agent is applied to glass fiber in the preparation of insulating articles and then heated to convert the tacking agent into a non-hygroscopic, water insoluble, amorphous, condensed aluminum phosphate polymer. The tacking agent resiliently tacks the glass fibers together so as to provide regain of shape after deformation of the fibers as by compression.

Abstract: There is disclosed a process for the fermentation by yeast of sugar to alcohol wherein a portion of the nutrient phosphate is provided by one or more condensed phosphates. It has been found that when condensed phosphates are employed as the nutrient source the fermentation rate increases. In addition, the rate increase is only observed when an increase in macronutrient elements is provided in conjunction with the condensed phosphates to compensate for the elements sequestered by the condensed phosphates.

Abstract: There is disclosed novel glass fiber particularly useful for preparing formed insulating articles having on the surface of the fibers an amorphous aluminum phosphate polymer wherein the polymer resiliently tacks the glass fibers together so as to provide regain of shape after deformation of the fibers as by compression. Also disclosed is a process for preparing glass fiber articles wherein the fibers are contacted with an ionic polymer which is then dehydrated to form an amorphous non-hygroscopic polymer.

Abstract: Compositions and process for activating metal surfaces prior to coating with zinc phosphate are disclosed. A Jernstedt salt concentrate is provided which can be employed to prepare Jernstedt salt baths of the type desired by combining the concentrate with additional alkali metal phosphate. Improved activation of metal surfaces are achieved by incorporating a chloride ion producing compound in the activating bath.
