This invention relates to a process for producing compounds derived from 9,10-Dihydro-9-Oxa-10-Phosphaphenantrene-10-oxide (DOPO). In particular, the invention relates to producing DOPO-derived compounds by reacting DOPO with diol compounds in the presence of a catalyst. This invention also relates to DOPO derived composition containing a high melting point diastereomer. The DOPO derived compounds may be useful as flame-retardants.

Thermally-activated cellulosic-based carbon is rendered more thermally stable by exposure to a halogen and/or a halogen-containing compound. Such treated cellulosic-based carbon is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100 C. to about 420 C.

Poultry carcasses are contacted with water treated with one or more specified dihalodialkylhydantoin biocides in a processing operation downstream from a scalding tank. The aqueous effluent from that downstream operation or from any location further downstream is recycled to the scalding tank. Surprisingly, the bromine residues from the dihalodialkylhydantoin biocides are much more thermally unstable than, for example, the commonly used microbiocide, sodium hypochlorite. Thus, the effluent from the scalding tank has its active bromine content significantly reduced before it is sent to a water purification facility wherein microbial action is used to reduce the BOD of the waste water before its release to the environment. Thus, injury to this desired microbial action is reduced. In addition, the recycle reduces water consumption in the overall poultry processing operation.
