    摘要： A composition of matter comprising a permanganate salt adsorbed or chemisorbed onto a solid alkaline support useful in a method for irreversibly removing or decreasing the amount of formaldehyde in the atmosphere. The composition further provides a color change indication when the formaldehyde absorbing characteristic is exhausted. The composition can be employed in molded, pellet, particle or powder form as, for example, in a respirator filter cartridge.

    摘要： The preparation of the azide of a carboxylic acid by reacting the hydrazide of the acid with nitrous acid is facilitated by using the organic solvent-soluble complex of an alkali metal nitrite with an ethylene oxide or propylene oxide cyclic polymer as the nitrous acid source. The improvement is particularly useful as a means for making peptides by the coupling reaction of an amino acid ester or other derivative with an acid azide in an anhydrous reaction medium.

    摘要： A controlled release and delivery system for a hydrophobic, water sensitive herbicide is produced by:(a) dissolving the herbicide in a volatile water-immiscible solvent;(b) introducing the solvent containing the herbicide dissolved therein to a latex dispersion comprising an aqueous continuous phase and polymeric discrete phase;(c) agitating the resultant mixture until the polymeric particles of the discrete phase absorb the herbicide; and(d) removing the solvent from the resultant mixture at reduced pressure.

    摘要： A family of composite materials consisting of a mineral filler and a synthetic polymer are provided which are characterized by properties similar to natural ivory. The ivory-like composite material contains about 25 to about 75 percent by weight of the mineral filler, preferably a calcium phosphate. In addition, the composite material contains about 75 to about 25 percent by weight of the polyamino acid, preferably an .alpha.-amino acid such as poly(gamma-methyl L-glutamate). The composite material is formed using in situ polymerization techniques, thereby ensuring intimate and homogeneous blending of the mineral and polymer phases as well as facile preparation at ambient temperatures. In addition, the ivory-like composite material is molded using an isostatic compression molding technique. The composite material may be molded to form virtually any desired shape for decorative or practical purposes, or for subsequent carving. The resulting ivory-like composite materials are characterized by properties similar to natural ivory.
