Which factor will affect the quotation price of2-methyltetrahydrofuran in domestic and oversea markets?
The main factor affecting the price is the supply and demand relationship between upstream and downstream industry. At present, the Chinese environmental policy will directly affect the production of the furfural factories. Enterprises which fail to meet the environmental standards cannot produce. So totally, the quantities of the supplying factories reduced, which resulted to the shortage supplying. Till now, the price of furfural is in high price level and it is not easy to purchase. Therefore, the cost for 2-methylfuran manufacturers become higher and higher. 2-methylfuran is as the raw materials of 2-methyltetrahydrofuran, so the price of 2-MeTHF is higher and higher. On the other hand, the production of 2-methyltetrahydrofuran is mainly concentrated in China, so the changing of domestic price directly affects the price of 2-methyltetrahydrofuran in oversea market.

What are the characteristics of furan resin for casting?
Furan resin for casting reaches the international advanced level, which is the environmental protection product, and the variety is complete.
The furan resin is suitable for cast steel, cast iron and non-ferrous alloy parts. Its color is light yellow to brownish red. The characteristics are as followed:
a: Low viscosity, easy to measure. Easy to mix with sand, casting sand flow good.
b: Low free formaldehyde content, lower odor, improving working conditions of workers, reducing environmental pollution.
c: High specific strength can reduce the amount of resin and reduce the cost. And it’s good to improve the quality of casting.
d: Good collapsibility of casting sand and reduce the work of sand cleaning.
e: High precision casting size, clear profile, smooth surface, reduce sand cleaning time, improve labor efficiency.

A comparison of 2-methyltetrahydrofuran and tetrahydrofuran which are used in the grignard reaction
The grignard reagent can react with the compound such as aldehyde and ketone, and then hydrolyze into alcohol. The kind of reaction is called grignard reaction.
Usually, the grignard reagent reacts with the aldehyde to form the secondary alcohol.
2-methyltetrahydrofuran of Shandong Yino Biologic Materials Co., Ltd. is mainly used in grignard reaction.
The properties of tetrahydrofuran, which is also used in the grignard reaction, are compared as followed.
First of all, 2-methyltetrahydrofuran is not soluble in water and it can be mostly recyclable.
Secondly, compared with tetrahydrofuran, 2-methyl tetrahydrofuran in the solubility of magnesium is much higher than THF, which means using less 2-Methf.
Last, since the structural complexation of 2-methyltetrahydrofuran reagent used in grignard reaction is more active.
In the other hand, 2-methyltetrahydrofuran is preferred if in allyl and benzyl reagents. What’s more, the purity if 2-methytetrahydrofuran can reach 99%min.
How to guarantee the quality of furan resin when purchasing.
Furan resin is mainly used in various materials resistant to chemical corrosion. The industrial value of furan resin is very high. It is commonly used to make corrosion-resistant cement and other materials. The mechanical properties of furan resin and other materials can be enhanced by mixing them. But how can we guarantee the quality of furan resin when we buy it? We choose the furan resin which is produced by normal factory, pay attention to the nitrogen content, brittleness and water content of furan resin, and guarantee the quality of furan resin.
The core material to determine the properties of coated sand
Resin is the most important and core material to determine the properties of coated sand. The lower the amount of resin in a certain strength, the more likely the resin will break up after casting. So the resin with low viscosity, high length and suitable polymerization speed should be selected as high strength phenolic resin, which round phenolic resins are more suitable than strip or sheet phenolic resins. Low viscosity, high flow length, round resin is easier to mix with round sand grains, to ensure the combination of resin and sand grains, so that the best binding effect of the resin, to achieve the purpose of using less resin finally.
