    摘要: A process for making an alkali metal alkoxide (e.g. sodium alkoxide) of a halogen-substituted alcohol (e.g. fluorine-substituted alcohols) by dispersing an alkali metal (e.g. sodium) in a cycloalkane (e.g. cyclohexane) containing a phenol (e.g. o-allylphenol) and adding the resultant dispersion to an ether (e.g. THF) solution of a halogen-substituted alcohol. The resultant alkali metal haloalkoxide solution contains phenoxides and can be reacted with a phosphonitrilic chloride polymer to introduce haloalkoxide and phenoxide substituents.

    摘要: A concentrated liquid biocide composition is produced by a continuous process. The process comprises continuously feeding into mixing apparatus (i) bromine chloride and (ii) an aqueous solution of alkali metal salt of sulfamic acid. These are proportioned to produce an aqueous product having an active bromine content of at least 100,000 ppm (wt/wt), and an atom ratio of nitrogen to active bromine from (i) and (ii) greater than 0.93:1. The desired product is withdrawn from the mixing apparatus at a rate sufficient to enable the continuous feeding to be maintained. Thus, the withdrawal of the product can be continuous or intermittent, depending upon the type of mixing apparatus being used.

    摘要: Contaminants in spent nitric-sulfuric nitration acid can be removed by mixing the spent acid with urea and heating to 75.degree.-150.degree. C. Off-gas from the spent acid/urea reaction is passed through a Group IB, VB, VIB or VIII metal containing catalyst to decompose nitrous oxides and the so-treated off-gas is contacted with spent acid, denitrated spent acid, or fresh sulfuric acid, and optionally air (i.e. oxygen), to absorb oxides of nitrogen. The spent acid scrubbing fluid is then subjected to the same process for removing contaminants.
