The instant invention describes a method for crystallizing (-)-6-chloro-4-cyclopropylethynyl-4-trifluoromethyl-1,4-dihydro-2H-3,1-benzoxazin-2-one from a solvent and anti-solvent solvent system and producing the crystalline product. The desired final crystal form, Form I, can be produced when using methanol or ethanol. Form II is isolated from 2-propanol and can be converted to the desired crystal form at low drying temperatures, such as between about a temperature of 40 C. and 50 C.

A method of grouting formations with a cementitious material comprising microfine ground slag is useful for stabilizing and strenghtening soil and rock formations as well as underground structures associated with buildings, tunnels and dams. A composition is provided which comprises water, a dispersant, slag and an accelerator to activate the slag. The method and composition are particularly useful for preventing permeation of water such as for grouting dam curtains and containing and stabilizing hazardous wastes including nuclear waste material.

Disclosed is a novel composition comprising water, ground blast furnace slag and a low molecular weight polymeric dispersant. The dispersant is a polymer of acrylic acid, having a molecular weight between 1000 and 20,000, and being in the form of the acid or the salt of an alkali metal or ammonia. A process for preparing a dispersion having the novel composition is also disclosed.

This invention is concerned with an aqueous liquid composition comprising unsaturated monomers including (1) magnesium diacrylate and/or calcium diacrylate, (2) a polyol monoacrylate selected from hydroxyethyl acrylate and hydroxypropyl acrylate, and (3) a polyethylenically unsaturated monomer copolymerizable with (1) and (2) to produce covalent cross-linking bonds in the copolymer besides the ionizable magnesium bonds. The weight ratio of (3) to the sum of (1) and (2) is in the range of about 3:97 to about 5:95. Examples of monomers that can be used as part or all of component (3) include N,N'-methylene-bis-acrylamide and ethylene glycol diacrylate. The relative proportions between the several monomers are selected to provide on polymerization a cross-linked vinyl addition polymer gel containing both covalent (non-ionic) cross-linking bonds and ionic cross-linking bonds and the relative proportions between the several components are predetermined to render the composition suitable for application by conventional mixing packer equipment hereinafter described. In such equipment, means is provided to direct a second aqueous solution or suspension containing a water-soluble free radical initiator, such as a persulfate or peroxide, separately but concurrently with the first monomer-containing solution to a common distributor head of the movable packer positioned in the sewer conduit adjacent the joint or crack to be repaired. The monomer solution is provided with a tertiary amine which serves as a reducing agent, thereby providing a redox polymerization system so that when the two liquids mix, upon discharge from the head, a rapid polymerization to a polymer gel occurs at the ambient temperature.

A gel-forming composition of matter comprising an aqueous solution of a mixture of certain percentages of monomeric acrylamide and monomeric N,N' methylenebisacrylamide and a polymerization catalyst and containing certain percentages of an unfired natural diatomaceous earth having a certain particle size is used in treating earthen formations around the joints of sewer pipes, whereby fluid loss from the composition into the earthen formation is substantially reduced.

This invention is concerned with a method of grouting sewer conduits by using an aqueous liquid composition comprising unsaturated monomers including (1) magnesium diacrylate, (2) an alkali metal (sodium or potassium) monoacrylate in a weight ratio of (1):(2) from about 90:10 to about 70:30, and (3) a polyethylenically unsaturated monomer copolymerizable with (1) and (2) to produce covalent cross-linking bonds in the copolymer besides the ionizable magnesium bonds. The weight ratio of (3) to the sum of (1) and (2) is in the range of about 3:97 to about 5:95. Examples of monomers that can be used as part or all of component (3) include N,N'-methylene-bis-acrylamide and ethylene glycol diacrylate.
