Abstract: Processes for the separation of water from a mixture of water with other components, comprising the following steps: A) providing feed material FM comprising water and at least one a nonionic surfactant S in an amount of 0.1 to 1000 ppm by weight based on the feed material FM, B) subjecting said feed material FM to a distillation step using a falling film evaporator.

Abstract: The present invention relates to a method for the determination of a concentration (C) of a polyacrylic acid (PAA) in an aqueous medium (AM) wherein the determination is performed photometrically in the presence of a dye (I). The present invention furthermore, relates to a method for the determination of a concentration (C) of a polyacrylic acid (PAA) in an aqueous medium (AM) wherein at least two different transmittance values are measured using at least two different wavelengths and wherein the at least two different transmittance values are analyzed to determine the concentration (C) of the polyacrylic acid (PAA). The present invention also relates to the use of a dye (I) for the determination of the concentration (C) of a polyacrylic acid (PAA).

Abstract: The present invention relates to amino-functionalized mesoporous silica. The present invention provides amino-functionalized mesoporous silica having hexagonal platelet morphology with short channels perpendicular to the platelet. The lengths of the channels are preferably 10˜1000 nm. The present invention also provides a method for preparing amino-functionalized mesoporous silica having hexagonal platelet morphology comprising a series of steps in sequence which are reactive gel preparation before subjected to the microwave, microwave heating for co-condensation reaction and crystallization, and solvent extraction for surfactant removal. The direct co-condensation approach with microwave heating and adoption of sodium metasilicate as silica source can give great advantage in the view of economy and environment.
