Disclosed are solid forms of 1-[(2-chloro-5-thiazolyl)methyl]-3-(3,5-dichlorophenyl)-2-hydroxy-9-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidinium inner salt (Compound 1). Methods for the preparation of solid forms of Compound 1 and for the conversion of one solid form of Compound 1 into another are disclosed. Disclosed are compositions for controlling an invertebrate pest comprising a biologically effective amount of a solid form of Compound 1 and at least one additional component selected from the group consisting of surfactants, solid diluents and liquid carriers. Compositions comprising a mixture of a solid form of Compound 1 and at least one other nematocide, insecticide and/or fungicide are also disclosed. Also disclosed are methods for controlling invertebrate pests comprising applying to a plant or seed, or to the environment of the plant or seed, a biologically effective amount of a solid form of Compound 1.

Solid forms of a pyrido-pyrimidinium inner salt

Disclosed are solid forms of 8-chloro-N-[(2-chloro-5-methoxyphenyl)sulfonyl]-6-(trifluoromethyl)-imidazo[1,2-a]pyridine-2-carboxamide (Compound 1). Methods for the preparation of solid forms of Compound 1 and for the conversion of one solid form of Compound 1 into another are disclosed. Disclosed are nematocidal compositions comprising a nematocidally effective amount of a solid form of Compound 1 and at least one additional component selected from the group consisting of surfactants, solid diluents and liquid carriers. Compositions comprising a mixture of a solid form of Compound 1 and at least one other nematicide, insecticide and/or fungicide are also disclosed. Also disclosed are methods for protecting a plant from nematodes comprising applying to the plant, or portion, or seed thereof, or to the growing medium of the plant, a nematocidally effective amount of Compound 1 comprising the polymorph Form A.

Solid forms of nematocidal sulfonamides

Processes for producing polytrimethylene ether glycol and copolymers thereof are provided wherein, by condensing and recycling at least a portion of the vapor phase produced as the reaction progresses, the yield loss and polymer color are reduced.

Processes for producing polytrimethylene ether glycol and copolymers thereof

This invention relates to a process for preparing polytrimethylene ether glycols or copolymers thereof by a polycondensation reaction using at least one acid catalyst, wherein the temperature of the reaction is controlled such that the average temperature during the first half of the reaction is higher than the average temperature during the second half of the reaction.

Preparation of polytrimthylene ether glycol or copolymers thereof

This invention relates to a process for preparing polytrimethylene ether glycols or copolymers thereof having a number-average molecular weight of at least about 250 g/mole by a polycondensation reaction using at least one acid catalyst.

Preparation of polytrimethylene ether glycol or copolymers thereof

This invention relates to an improved cake-filtration solid-liquid separation process wherein the improvement comprises simultaneously subjecting the solid-liquid mixture to a homogeneous magnetic field, a magnetic field gradient or both and cake-filtration to accomplish separation.

Magnetic field enhanced cake-filtration solid-liquid separations

This invention relates to apparatus for carrying out continuous or batch centrifugation solid-liquid separation processes in which the solid-liquid mixture is subjected to magnetic field gradients and centrifugation.

Apparatus for magnetic field gradient enhanced centrifugation

This invention relates to a continuous or batch centrifugation solid-liquid separation process comprising simultaneously subjecting the solid-liquid mixture to localized magnetic field gradients and the centrifugation and to improved centrifugation solid-liquid separation processes wherein the improvement comprises simultaneously subjecting the solid-liquid mixture to a homogeneous magnetic field, a magnetic field gradient or both prior to and/or during the centrifugation.
