Embodiment 1

[0026] The sugarcane waste molasses diluted with drinking water to a concentration of 30% (volume) is pumped into the resin column equipped with macroporous adsorption resin, and the chlorogenic acid etc. Separated from molasses and adsorbed on the resin; the resin after adsorbing chlorogenic acid and other substances was washed with deionized water, and CuCl with a volume of 4 times the volume of the resin and a concentration of 8 mmol / L was added at 70 °C 2 The solution is used as an eluent, and the resin is eluted at a flow rate of 2 times the volume of the resin bed. While the resin is eluted, it reacts to form copper chlorogenic acid, which is desorbed from the resin to obtain an eluted solution containing copper chlorogenic acid and other substances. liquid; the eluent containing copper chlorogenic acid and other substances is packed into a glass silica gel chromatography column (chromatographic silica gel column specifications: inner diameter 1000mm, column length 10000m...

Embodiment 2

[0028] The starch molasses with a concentration of 40% (volume) diluted with drinking water is packed into a resin column, and the catechin etc. (phenolic acids) and other substances in the starch molasses are separated from the starch molasses and adsorbed On the resin; after the above-mentioned resin adsorbed with catechin and some impurities was eluted with deionized water, CoCl with a volume three times the volume of the resin and a concentration of 3 mmol / L was added at 60°C. 2 The solution is used as a regeneration agent, and the resin is eluted at a flow rate of 3 times the volume of the resin bed, and cobalt catechin is reacted at the same time as the resin is eluted, and is desorbed from the resin to obtain an eluent containing cobalt catechin and other substances The eluent containing cobalt catechin and other substances is packed into a stainless steel silica gel chromatography column (chromatographic silica gel column specification: internal diameter 800mm, column l...

Embodiment 3

[0030] Beet molasses diluted with drinking water to a concentration of 35% (volume) is packed into a resin column, and succinic acid (phenolic acids) and some impurities in the beet molasses are separated from the beet molasses and adsorbed on On the resin; after the above-mentioned resin adsorbed with succinic acid and other substances was eluted with deionized water, ZnCl with a volume of 6 times the volume of the resin and a concentration of 2 mmol / L was added at 75°C 2 The solution is used as a regeneration agent, and the resin is eluted at a flow rate of 3 times the volume of the resin bed, and the resin is eluted and reacted to generate zinc succinate, which is desorbed from the resin to obtain an eluent containing zinc succinate and other substances; The eluent containing zinc succinate and other substances is loaded into a glass silica gel chromatography column (chromatographic silica gel column specification: inner diameter 500mm, column length 5000mm) for silica gel a...

Abstract

The present invention provides a gooey phenolate preparation method, including the following steps: using alkaline anion resin to absorb phenolic acid and the like substance with minus charge in the gooey; and then adding metal salt solution or alkali liquor in the resin adsorbed with gooey phenolic acid material for eluting, to obtain an eluent containing the gooey phenolate as principal ingredients; using silica gel to adsorb the gooey phenolate and other components in the eluent, using solvent for the desorption and purification of phenolate adsorbed on the silica gel, collecting separation component containing gooey phenolate at the same time of desorption; crystallizing, washing and drying the separation component containing gooey phenolate, finally obtaining the gooey phenolate crystal. The invention has simple process, environmentally friendly energy-saving performance, full utilization of accessory substances in the industry, substantially reduced pollution to the environment in the production processes and cost, short development cycle, high economic benefit and stronger operability.

Description

technical field [0001] The invention relates to the field of sugar production, in particular to the extraction and separation of phenolic acid substances in by-product molasses obtained after sugar extraction from sugar materials such as sugar cane, sugar beet and starch, and a preparation method of phenolic acid salts. Background technique [0002] Sugar production from sugar cane and sugar beets yields more than 3% of the waste honey. For example, China produced about 4.2 million tons of waste molasses in the 2007 / 2008 sugar production period. Due to the accumulation of complex phenolic pigments in the waste molasses and the Maillard reaction pigments and alkali-degraded pigments produced during the processing, the downstream product wastewater produced by molasses fermentation has extremely high color value and is difficult to treat, which is harmful to the environment. cause serious pollution. [0003] The research and development of phenolic acids is a hot topic in the...
