A method of reacting amine compounds with halons and perhalogenated compounds, resulting in the conversion of these ozone-depleting species into non-volatile salts and a variety of other amine derivatives is disclosed.

Method for destruction of halons

Glyphosate formulations which are effective even when employed at dosages below the dosage currently recommended for post-emergent herbicidal or plant growth regulant use are described. They are formulated as water solutions or powders or granules of (a) one or more agriculturally acceptable salts of glyphosate, e.g., amine, ammonium, alkali metal, alkylsulfonium, alkylphosphonium, sulfonylamine, and/or aminoguanidine salts of glyphosate; (b) at least one water-soluble long chain aliphatic hydrocarbyl dimethyl amine oxide in which the hydrocarbyl group is a linear or substantially linear saturated or olefinically unsaturated aliphatic group having in the range of about 8 to about 22 carbon atoms; and (c) at least one water-soluble quaternary ammonium halide having in the range of about 8 to about 40 carbon atoms in the molecule.

Glyphosate formulations which are effective even when employed at dosages below the dosage currently recommended for post-emergent herbicidal or plant growth regulant use are described. They are formulated as water solutions or powders or granules of (a) one or more agriculturally acceptable salts of glyphosate, and (b) one or more particular types of quaternary ammonium compounds. The quaternary ammonium compound(s) are water-soluble compounds represented by the formula:

A quaternary ammonium halide is prepared by reacting a substituted or unsubstituted haloalkane with a tert-amine in a mol ratio not higher than 1.1/1 in the absence of a solvent and at a temperature such as to maintain the reaction mixture liquid.

Process for preparing quaternary ammonium compounds

Preceramic polysilazanes which (1) are composed of silicon, nitrogen, and hydrogen, (2) can be isolated and redissolved in common organic solvents, and (3) are capable of providing a high ceramic yield when pyrolyzed are prepared by reacting a mixture of one molar proportion of a tetrahalosilane, preferably tetrachlorosilane, and at least 4.5 molar proportions of a dihalosilane, preferably dichlorosilane, in an organic solvent. Ceramics obtained from the polysilazanes are nanoporous, amorphous silicon nitride ceramics having high purity.
