Abstract: The invention comprises a flame-inhibiting and fire retarding substance consisting of a bromine-containing tricresyl phosphate which contains bromine in the benzene nuclei and in which the bromine content is from 50% to 65% by weight of the bromine-containing substance.  The bromine-containing substance is a resinous product and may be obtained by reacting a sufficient amount of bromine with tricresyl phosphate at elevated temperature until the required amount of bromine has combined or by brominating cresylic acid and reacting the brominated cresols formed with phosphorus oxychloride, the bromination of cresylic acid being carried out to such an extent that the final phosphate product contains the required amount of combined bromine.  The tricresyl phosphate which is brominated is defined as a liquid mixture of isomeric tricresyl phosphates.  In an example tricresyl phosphate is mixed with bromine and the mixture allowed to stand overnight in the presence of a crystal of iodine as catalyst and then heated to 80-90 DEG C. for about 8 hours to yield a product containing 50.4% by weight of bromine.  The products may be used as flame inhibitors and fire - retardants for chlorine-containing substances such as polyvinyl chloride, chlorinated rubber and chlorinated waxes as disclosed in Specification 874,905.
