Inventor: BLIZNJUK N K
IPC: C01B25/163
Filed: 1995-03-10
Abstract: FIELD: production of inorganic and organic substances. SUBSTANCE: method is based on interaction of phosphorus trichloride with tert-butanol at molar ratio 1:3, process being carrying out in presence of phosphorous acid taken in amount from 0.1 to 1 mol per 1 mol of final product. Reaction is effected by way of adding phosphorus trichloride to boiling tert-butanol- phosphorous acid mixture. Under these conditions, crystallization of final product occurs yet in the course of reaction as formation of the product proceeds. In absence of phosphorous acid initially added, its crystallization takes place usually after termination of the process, sometimes only upon addition of "seed". In such a case crystallization occurs practically instantaneously and is accompanied with large liberation of heat which leads to a danger of outburst of reaction mixture. So introduction of phosphorous acid in the beginning of process ensures its safety. Crystalline acid obtained is practically insoluble in tert-butyl chloride. This fact enables practically quantitative isolation of the two products with high purity degree using no other procedure as simple decantation. EFFECT: increased yield of phosphorous acid and provided isolation of pure coproduct.

Abstract: FIELD: civil engineering. SUBSTANCE: sealing includes subsequent injecting the grouting mortar through injectors. The injecting is carried out to the depth of the structures through a group of point like injectors fastened to the earlier drilled wells of the structure. The injectors are hydraulically interconnected within the sealing portion. There are three subsequent stages of injecting. The first and second stages use grouting mortar of similar composition but different water/cement ratio equal to 0.65 - 0.85 and 0.35 - 0.55 respectively. The mortar contains Portland cement, micro-silica, SURFACE ACTIVE SUBSTANCE, quartz sand of 0.140 mm and (0.140 - 0.315) mm size, and complex mineral addition - the product of joint milling the aluminate cement of 500 grade containing 12 - 15 % three-calcium aluminate of cement weight, calcium sulphoaluminate, and quartz sand of not more than 0.140 mm size in ratio 1:1:1 with the following content of the components in the mortar (% by weight): 35.5 - 40.0 Portland cement of 500 grade; 1.5 - 3.5 micro-silica of (25-35)x1000 square centimeters per gram specific surface; 25.0 - 35.0 quartz sand of less than 0.140 mm size; 35.0 - 38.0 quartz sand of (0.140 - 0.315) mm size; 0.25 - 1.5 surface active substance; 4.5 - 6.5 the above complex mineral addition; the balance being water. At the final stage of injecting used is grouting mortar of the following content (% by weight): 30.5 - 43.5 Portland cement of 500 grade; 1.5 - 3.5 micro-silica of (25-35)x1000 square centimeters per gram specific surface; 30.5 - 33.5 quartz sand of less than 0.140 mm size; 0.5 - 2.0 surface active substance; 2.5 - 4.5 the above complex mineral addition; the balance being water. The method is implemented at each stage of injecting the mixers under the following sequence. First during 15 - 20 sec the pressure is increased up to operating one equal to 2.0 - 6.0 kilo per square centimeter, which is stopped on achieving the constant absorbing of the grouting mortar at the level of 0.01 - 0.05 l per minute. The injecting under the stopped operating pressure is performed for 3 - 10 minutes. Then the pressure is smoothly decreased during 10 - 12 sec to zero and then the injection system becomes disconnected from the injectors. The injectors are withdrawn from the wells, and the wells are plugged by filling with concrete mortar of the following content: 35.5 - 40.5 Portland cement of 500 grade; 1.5 - 3.5 micro-silica of (25 - 35)x1000 square centimeters per gram specific surface; 7.5 - 9.5 milled quartz sand of (3.5 - 4.5)x1000 square centimeters per gram specific surface; 43.5 - 54.0 quartz sand of (0.140 - 0.315) mm size; 4.5 - 5.5 the above complex mineral addition; the balance being water. Then all compression stages are performed for groups of injectors of the following sequence. EFFECT: higher efficiency.
