Abstract: The present invention provides a method for treating hexamine waste water. The method includes subjecting the waste water to conditions sufficient to remove volatile constituents, passing the waste water through a cation exchange resin capable of absorbing cations, and optionally either subjecting the waste water to a bacteria culture capable of consuming formaldehyde in the presence of an organic nutrient for the bacteria or subjecting the waste water to ultraviolet light in the presence of an oxidizing agent. The method may include both optional method steps, but must include at least one. The method also includes regenerating the cation exchange resin to remove the absorbed cations and reform the cation exchange resin. The present invention also provides an apparatus for treating hexamine waste water.

Abstract: A method for making sulfur-containing organosilanes of Formula (I):(R.sup.1).sub.3 -Si-R.sup.2 -S.sub.n -R.sup.2 -Si-(R.sup.1).sub.3wherein each R.sup.1 is independently selected from the group consisting of a C.sub.1 -C.sub.4 alkyl, a C.sub.1 -C.sub.4 alkoxy, a C.sub.5 -C.sub.8 cycloalkyl, a C.sub.5 -C.sub.8 cycloalkoxy, a phenyl group, or a phenoxy group, a benzyl group or a benzyloxy group; R.sup.2 is a C.sub.1 -C.sub.4 alkyl; and n is a number from 3-4. The method comprises (a) dissolving an alkali metal in a C.sub.1 -C.sub.4 alcohol to provide an alkali metal alcoholate, (b) reacting hydrogen sulfide with the alkali metal alcoholate of step (a) to provide an alkali metal hydrosulfide, (c) reacting an alkali metal with the alkali metal hydrosulfide of step (b) to provide an alkali metal sulfide, (d) reacting sulfur with the alkali metal sulfide of step (c) to provide an alkali metal polysulfide, and (e) reacting a compound of Formula (II): X-R.sup.2 -Si(R.sup.1).sub.3, wherein R.sup.1 and R.sup.
