The effect of the temperature of the exothermic reaction of the neutralisation by gaseous ammonia of acrylate-production mother liquor on the physical state of the high-molecular-weight sulphonated organic matter was studied on a pilot and on an industrial unit. The established optimum conditions for processing acrylate-production mother liquor by means of neutralisation using gaseous ammonia (maximum temperature 90°C, pH 4.2-5.5) have been introduced into ammonium sulphate production, making it possible to avoid “ageing” of the high-molecular-weight sulphonated organic matter with transition into the suspended state, and to prevent technological difficulties.
