Abstract: 1393223 Preparing tris-(2-haloalkyl)phosphites OLIN CORP 23 Aug 1973 [25 Aug 1972] 40032/73 Heading C2P A tris-(2-haloalkyl)phosphite which is optionally additionally substituted by chlorine in the haloalkyl groups is obtained by reacting a phosphorus trihalide in which the halogen is Cl or Br or a mixture thereof with an alkylene oxide which has a 1,2-epoxide ring and which is optionally substituted by chlorine in the presence of ethylene dichloride as solvent and at a temperature not exceeding 45‹ C. The process results in a reduction of the amount of phosphonate by-products formed and a still further reduction of such by-product formation is achieved by shortening the time of addition of the alkylene oxide to the phosphorus trihalide. It is preferred to exclude moisture from the reaction medium, e.g. by using a blanket of nitrogen gas. Examples are given for the reaction of ethylene oxide and PCl 3  to form tris- (2-chloroethyl)phosphite which is useful as a flame-retardant for polyurethane foam. The products may be reacted with a halogen gas to form a bis-(2-haloalkyl)phosphorohalidate which can be reacted with an alkylene glycol to yield a tetrakis - (2 - haloalkyl)alkylene diphosphate which is useful as a flame-retardant for polyurethane foam.

Title: Improvements in or relating to methods and apparatus for preparing sodium sulphate, more especially in the manufacture of synthetic textile products from viscose
IPC: B01D9/00
Filed: 1960-11-22
Abstract: <PICT:0964794/C1/1> A process for the production of anhydrous sodium sulphate from aqueous sodium sulphate solutions comprises the steps of cooling or vacuum evaporating the aqueous solution to crystallize sodium sulphate decahydrate, and melting the decahydrate crystals to precipitate anhydrous sodium sulphate, wherein a refrigerating system, having a closed cycle of a vaporizable heat-transfer liquid through an evaporator, a compressor, and a condenser, is provided in order to extract heat from the solution being crystallized, or from the vacuum evaporated vapours, by the evaporator of the refrigerating system, and to supply said extracted heat to the crystals being melted by the condenser of said refrigerating system. Fig. 2 shows the embodiment in which the crystallization is achieved by cooling. Aqueous sulphate solution entering evaporator 2 via pipe 1 is cooled by evaporation of a refrigerant in a coil 4 located within evaporator 2.  The separated decahydrate crystals are separated in centrifuge or filter 6 and then fed to a condenser 7.  The refrigerant evaporated in coil 4 is compressed in 3 and delivered to a heating coil 8 in condenser 7 in which it condenses, its heat being utilized for melting the decahydrate to precipitate anhydrous sodium sulphate. The condensed refrigerant returns via pressure reducing valve 5 to the cooling cycle.  The anhydrous sulphate is separated in centrifuge or filter 9 and extracted via pipe 10, while the mother liquors return via 11 to evaporator 2. Pipe 12 discharges sulphate-free liquid from evaporator 2. Fig. 3 (not shown) illustrates the alternative embodiment whereby crystallization of the decahydrate is achieved by vacuum evaporation instead of by direct cooling.
