Abstract: This idea relates to the synthesis of salts of dodecahydrododecaborate B12H12 (2-). In the proposed process a metal hydride is reacted with an alkyl borate in the presence of a Lewis base to produce Lewis base-borane compex, which is thermally decomposed to produce salts of B12H12 (2-), while alkyl borare is recovered from the reaction by-product and is recycled.

Abstract: The disclosure relates to the synthesis of salts of dodecahydrododecaborate B12H12 (2-), which comprises reacting a) at least one Bronsted acid or Lewis acid b) at least one tetrahydroborate selected from the class consisting of alkali metal tetrahydroborates and alkaline earth tetrahydroborates, and c) at least one Lewis base selected from those of the formulas consisting of RO(CH2CH2O)R?, R?SR?, RR?R?N and RR?R?P.

Abstract: A process for removing nitroaromatic and nitrophenolic compounds from an alkaline wastewater stream generated in a process for the nitration of aromatic compounds by the mixed acid technique, which comprises(a) adjusting the pH of the aqueous alkaline waste stream containing nitroaromatic and nitrophenolic compounds to a range from about 2 to 4.5,(b) contacting the acidic aqueous stream with sufficient hydrogen peroxide and ferrous ion under conditions to effect oxidation of the nitrophenolic compounds,(c) adjusting the acidic, oxidized aqueous waste stream having a reduced nitrophenolic content to about pH .gtoreq.4, and(d) contacting the aqueous waste stream with a carbon adsorbent.

Abstract: This invention relates to improved wet oxidation process for the destruction of organic components in a wastewater stream contaminated with inorganic salts. In wet oxidation, the wastewater stream is contacted with an oxygen-containing water stream at elevated temperatures and pressures. The improvement for treating aqueous wastewater streams contaminated with inorganic salts wherein the organic contaminants are present in an amount from about 0.5 to 2% by weight resides in oxidizing the organic components in a tubular reactor at a temperature ranging from 325.degree. C. to not more than 370.degree. C. and a pressure ranging from 220 to 345 bar. The oxidation reaction is carried out in a reaction time of 5 minutes or less.
