An industrial waste salt resourceful treatment method comprises the following steps: the industrial waste salt is sequentially subject to dissolving, chemical pre-purification, deep purification, organic matter concentration reduction, adsorption and oxidation decolorization and multi-effect evaporative crystallization to respectively obtain sodium sulfate, sodium chloride and sodium nitrate crystals; the crystallization temperature of sodium sulfate is in a range of 75° C. to 85° C.; the crystallization temperature of sodium chloride is in a range of 60 to 70° C.; and the crystallization temperature of sodium nitrate is in a range of 45° C. to 55° C. An industrial waste salt resourceful treatment device is further provided.

This invention is related to an improvement in the process of filtrate extension of a reaction where at least a set of filtrates of a set of reaction are mixed together to form for a filtrate extension thereby the reaction yields higher order chemical auxiliaries and the reaction is observed that either as convergent or divergent pathway substrate reacts to give qualitative products quantitative, conversions and very less in numbers. Among qualitative conversion reaction filtrate takes pivotal role in synthesizing chemical auxiliaries.

A method for synthesizing two-dimensional (2D) nanosheets comprises heating a bulk material in a solvent. The process is scalable and can be used to produce solution-processable 2D nanosheets with uniform properties in large volumes.

This invention relates to a method of forming crystals of chemical molecules. The methods are effective even when only very small amounts of a compound are available and can be used to explore the experimental crystallisation space including screening for optimal crystallisation conditions such as for polymorphic phases, salts, solvates and co-crystals of chemical molecules and to provide single crystals for structural determination of unknown molecules by single crystal X-ray crystallography.

This invention relates to a process for separating components of skim milk, in particular to the extraction of milk proteins and lactose from skim milk powder. The method involves combining skim milk powder with water, raising the temperature of the resulting mixture followed by cooling the mixture to produce a viscous casein fraction and a less viscous lactose fraction, and then separating the two fractions with optional purification.
