Aqueous compositions, aqueous cutting fluid using the same, method for preparation thereof, and cutting method using the cutting fluid

An aqueous cutting fluid which can reduce the impact on working environment and the global environment, and can achieve both preventing precipitates from becoming a hard cake and keeping high dispersibility for abrasive grains is provided. Such an aqueous cutting fluid is obtained by a method comprising dispersing abrasive grains (G) in an aqueous composition comprising a dispersion medium (M) containing a hydrophilic alcohol compound such as ethylene glycol, a lipophilic alcohol compound such as propylene glycol and water, and silica colloid particles dispersed stably in the medium. The dispersion medium (M) is odorless and not flammable. The abrasive grains (G) may settle out after a time, but they do not closely contact with one another, and therefore the resulting precipitates do not become a hard cake, which allows the re-dispersion and reuse of precipitated grains. The instant aqueous cutting fluid is inherently low viscous, and the reduction of viscosity owing to the contamination of water and the increase of viscosity owing to contamination of shavings are both moderate. As a result, the cutting fluid has a long life. And articles which have been cut using the cutting fluid can be washed with water. Further, as the dispersion medium (M) is a biodegradable low molecular weight organic compound, a waste liquid from a process using the cutting fluid can be disposed with an activated sludge.

Energy-saving and emission-reducing technique for producing propane epoxide by using hydrogen peroxide epoxidation propylene

The invention relates to an energy-saving and emission-reducing technique for producing propane epoxide by using hydrogen peroxide epoxidation propylene, belonging to the field of petrochemical technology. The technique comprises a reaction part, a separation part and a tail gas treatment part, and is characterized in that propylene and hydrogen peroxide have an epoxidation reaction through a Ti-Si molecular sieve at medium pressure and low temperature; the propylene and solvent have higher recovery rate, the propane epoxide meeting the requirement of commercial-grade purity can be obtained by extractive distillation, and the joint product of propylene glycol monomethyl ether can be prepared by azeotropic distillation and purification; after part of tail gas is condensed and absorbed and the propylene is recovered, the tail gas reaches the standard and is discharged; extracting agent, absorbing agent and entrainer which are needed by the technique are in closed cycle in the process flow; and medium-pressure operation is adopted by a propylene tower to ensure water-cooling on the top of the tower, and thermal energy can be recovered by multiple-effect rectification and matching of streams. The technique has the effect and the advantage that the new energy-saving and environment-friendly technique for producing the propane epoxide can generate remarkable economic and social benefits.

Methods for preparing ethylene glycol from polyhydroxy compounds

This invention provides methods for producing ethylene glycol from polyhydroxy compounds such as cellulose, starch, hemicellulose, glucose, sucrose, fructose, fructan, xylose and soluble xylooligosaccharides.
