Abstract

The invention pertains to a process for manufacturing a cyclic urea adduct of an ethyleneamine compound, the ethyleneamine compound having a linear -NH-CH2-CH2-NH- group, the process comprising the steps of - in an absorption step contacting a liquid medium comprising an ethyleneamine compound having a linear -NH-CH2-CH2-NH- group with a CO2-containing gas stream at a pressure of 1 -20 bara, resulting in the formation of a liquid medium into which CO2 has been absorbed, - bringing the liquid medium to cyclic urea formation conditions, and in an urea formation step forming cyclic urea adduct of the ethyleneamine compound, urea formation conditions including a temperature of at least 120°C, wherein the total pressure at the end of the urea formation step is at most 20 bara, wherein the temperature in the absorption step is lower than the temperature in the urea formation step. It has been found that the process according to the invention makes it possible to obtain cyclic urea adducts in an efficient manner in the absence of metal-containing catalysts and to perform the process under relatively mild conditions, in particular relatively low pressure. More specifically, by separating the CO2 absorption step from the urea formation step, the CO2 absorption step can be carried out at relatively low temperatures and pressures. And because the CO2 is already present in the system at the beginning of the urea formation step, the pressure in the urea formation step does not need to be high.

Abstract

The present invention relates to a process to prepare a free-flowing salt product comprising sodium chloride (NaCl) and/or potassium chloride (KCl), wherein the salt product has a particle size of from 50 μm to 1000 μm,which process comprises the steps of (a) processing a source of pure NaCl, pure KCl, or mixture of salts, to form particles with an average size of less than 100 micrometer; (b) subsequently, compacting the particles from step a) using a pressure of from 40 to 400 MPa; and optionally, crushing the thus obtained particles;and (c) subsequently, absorbing one or more agents into the salt particles, characterized in that no agent is added in or during steps a) and b) or between steps a) and b).

Abstract

The present invention relates to a process to prepare N,N'-di(2-hydroxybenzyl) ethylenediamine-N,N'-diacetic acid and salts thereof (HBED) comprising a reaction between formaldehyde, ethylenediamine diacetic acid or a salt thereof (EDDA) and phenol, wherein the reaction mixture contains 0.2 to 1.1 molar equivalents of alkali metal ions on the basis of the molar amount of EDDA and the reaction mixture is processed by a step in which at least part of the organic compounds other than the formed HBED are removed from the reaction mixture, and optionally recycled, during which step at least 50% and up to and including 100% of the alkali metal ions in the reaction mixture are potassium ions, to products obtainable by such process and their use.

Abstract

The present invention is directed to a process for catalytic hydrodechlorination of dichloroacetic acid, wherein hydrogen gas is contacted with a liquid feed comprising dichloroacetic acid and monochloroacetic acid to form a product stream comprising monochloroacetic acid and an off gas stream comprising hydrogen chloride and hydrogen, and wherein the product stream is contacted with nitrogen gas so as to remove hydrogen gas present in the product stream.

Abstract

A dried rheology modifier composition comprises a swellable emulsion polymer and a water soluble support polymer. In one embodiment the swellable emulsion polymer is polymerized in the presence of the water soluble support polymer. In one embodiment the swellable emulsion polymer is blended with the water soluble support polymer. The drying can be accomplished by spray drying, resulting in a non-tacky powder having good shelf life. The dried rheology modifiers can be subjected to a further heat treatment which can result in a rheology modifier that imparts a short flow characteristic to product formulations. The swellable emulsion polymer can be alkali swellable or acid swellable. The water soluble support polymer can be a polysaccharide or a derivative thereof, or a polyvinyl acetate or derivative thereof.
