Definitions
- each X can be independently chloro or bro-mo or when taken together can form a bond, and the sum of chlorine and bromine atoms in the compound is at least two.
- This invention relates to a method for imparting flame resistance to fibrous materials. More particularly, the invention relates to the use of halogenated tripropargyl phosphates as flame retardants for fibrous materials.
- each X can be independently chloro or bromo or when taken together form a bond, each X can be a halogen radical or when taken together can form a bond, and the sum of X and X atoms in the compound is at least two.
- the flame retardants of the present invention are readily prepared by halogenation of tripropargyl phosphate.
- the tripropargyl phosphate is dissolved in a halogenated hydrocarbon solvent such as carbon tetrachloride, chloroform, methylene chloride, trichloroethylene, perchloroethylene and the like and a gaseous or liquid halogen is added to the solution.
- a halogenated hydrocarbon solvent such as carbon tetrachloride, chloroform, methylene chloride, trichloroethylene, perchloroethylene and the like.
- a gaseous or liquid halogen is added to the solution.
- the addition of at least two halogen atoms and preferably, at least four halogen atoms, to the compound is considered necessary to impart flame retardation activity to the compound.
- the halogens employed are chlorine and bromine; however, in the highly halogenated species, other halogens such as iodine and fluorine can additionally be employed, if desired.
- the degree of halogena- 3,783,016 Patented Jan. 1, 1974 tion follows the reaction stoichiometry. For example, when one mole of tripropargyl phosphate is reacted with three moles of chlorine, tri(2,3-dichloroallyl) phosphate is obtained. If, however, six moles of chlorine are employed, tri(2,2,3,S-tetrachloropropyl)phosphate is obtained.
- Typical flame retardants encompassed by the present invention are, for example,
- the flame retardant compositions of the present invention can be applied to fibers and fabrics in any suitable inert vehicle.
- these compounds are soluble in halogenated hydrocarbons such as carbon tetrachloride, chloroform, methylene chloride, trichloroethylene, perchloroethylene and the like as well as other non-aqueous solvents such as tetrahydrofuran.
- Solutions or dispersions containing the flame retardant compositions of the present invention in concentrations ranging from about 5 to about 10 percent by weight can be suitably employed.
- the flame retardant compositions can be applied to fibers and fabrics by any convenient means such as spraying, dipping, immersing, padding and the like. If desired, the flame retardant compositions can be admixed with synthetic polymeric materials and can be co-extruded therewith to form fibers exhibiting flame retardation. Generally, it is considered preferable to impart from about 5 to about 20% by Weight on a dry basis of the flame retardant composition to the fibers or fabrics being treated to obtain effective flame retardation.
- Typical fibers which can be treated are, for example, cotton, wool, silk, nylon, rayon, polyesters and the like.
- EXAMPLE V Into a cold solution of 21.2 g. (0.1 mole) tripropargyl phosphate in 100 ml. carbon tetrachloride was passed 49.5 g. (0.7 mole) chlorine gas over the course of two hours. The solution was allowed to stand overnight at ambient temperature. The solvent was removed under vacuum leaving 63.7 g. (100%) of OP (OCH CCl CCI H) 3 EXAMPLE VI The procedure in Example V was repeated using 21.2 g. (0.1 mole) tripropargyl phosphate, 21.3 (0.3 mole) chlorine gas in 100 ml. carbon tetrachloride. There was obtained 42.5 g.
- Example VII The procedure in Example V was repeated using 21.2 g. (0.1 mole) tripropargyl phosphate, 14.2 g. (0.2 mole) chlorine gas in 100 ml. carbon tetrachloride. There was isolated 35.4 g. (100%) of EXAMPLE VIII A solution of 5 g. of OP(0CH CBr CBr H) prepared as described in Example II, 45 g. tetrahydrofuran, 32.5 g.
- each X can be independently chloro or bromo or when taken together can form a bond, and the sum of chlorine and bromine atoms in the compound is at least tWO.
