First aid measures for furfural
Fufural (furyl formaldehyde) is an industrial chemical that is extracted from a variety of agricultural by-products, including corn cobs, oat and wheat bran, and sawdust. The word furfural is derived from the Latin word furfur, which means wheat bran, since this is where
Furfural was first discovered by J.W.Doeberiener in 1832, and it was industrially produced in the United States in 1922 for the synthesis of resins. As the name implies, furfural is an aldehyde made from bran. In fact, rice bran, wheat husks, cottonseed husks, corncobs and o
How Hydroxyethyl Cellulose is Used in Construction
Hydroxyethyl cellulose (HEC) is a water-soluble polymer compound, commonly used in coatings, cement mortar, tile adhesives, etc. in the construction field. HEC can increase the adhesion, fluidity and stability of materials, and improve the water resistance and weather resistance of m
How Is Dibenzoylmethane Used as An Analytical Reagent
Dibenzoylmethane can be used as an analytical reagent to detect the presence of metal ions such as aluminum, zinc, calcium, and magnesium. The principle is that dibenzoylmethane forms a complex with metal ions, which changes the color of the solution, so that quantitative a
Industrial Application of Dibenzoylmethane
In the PVC industry, Dibenzoylmethane can be used as a new type of PVC auxiliary heat stabilizer, which can absorb ultraviolet light above 290nm, has high light transmittance, is non-toxic and tasteless, and can be used together with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers to improve The initial coloring performance, transparency and long-term stability of PVC can effectively impro
Determination of furfural moisture content

Furfural as a polymerization inhibitor
Furfural as a polymerization inhibitor During extractive distillation, in order to prevent self-polymerization of butadiene, a certain amount of furfural is added to the solvent as a polymerization inhibitor.
Furfural is a compound produced by the reaction of biomass rich in pentose sugars in hemicellulose under strong acid catalysis. Used as a potential platform for the production of biofuels. In recent years, furfural has received special attention as a potential platform for the pro
Furfural has great potential for development
Furfural is a renewable product. The development of furfural industry can not only improve the utilization rate of corn cob, but also help promote carbon neutrality and carbon peaking. As the global energy transition accelerates, the demand for furfural will continue to grow. The global
The downstream products of furfural
Furfural is a commonly used excellent solvent and an important raw material for organic synthesis. It can be condensed with phenol to produce phenol furfural resin similar to bakelite. Some compounds derived from furfural are also useful chemica
Introduction of Hydroxyethyl Cellulose
Hydroxyethyl cellulose is a yellow powder product, easy to disperse and dissolve in cold water and hot water, and then form aqueous solutions with different viscosities. There are two grades of hydroxyethyl cellulose, one is industrial grade and the other is daily chemical grade. Industrial grade can only be used as a thickener in industrial coatings, while daily chemical grade can be added to shampoos, hair
Advantages of Hydroxyethyl Cellulose

Understand the retarding effect of cellulose ether
Cellulose ether will prolong the setting time of cement paste or mortar, and delay the hydration kinetics of cement, which is beneficial to improve the operability time of cement-based materials, improve the consistency of mortar and the loss of concrete slump over time, but may also cause Delays in construction progress are especially detrimental to mortar and concrete used in low temperature ambient conditions. Generally, the higher the content of cellulose ether, the longer the setting time of cement slurry and mortar, and the
