Oil prices doubled in 1 year, and Dichloromethane, Calcium hydrogen phosphate rose and fell

 

It can be expected that according to the current oil price trend, the crude oil price will remain for a period of time. The corresponding domestic chemical prices in China are not fundamentally volatile. Except for some of the supply and demand sides that are out of balance, the rest of the prices are basically maintained at the level of 2022.

The methylene chloride, epoxy resin, propylene oxide, urea, alumina, calcium hydrogen phosphate, polyvinyl alcohol, ethyl acrylate, methyl acrylate, crude benzene, etc. mentioned in the picture below are currently sold at CFI.

1. Dichloromethane with a large increase is an organic compound with a chemical formula of CH2Cl2. It is a colorless and transparent liquid with a pungent odor similar to ether. Slightly soluble in water, soluble in ethanol and ether, it is a non-flammable low-boiling solvent under normal use conditions, and is often used to replace flammable petroleum ether, ether, etc.

In industry, methylene chloride is prepared by reacting natural gas with chlorine gas, and purified by rectification. It is an excellent organic solvent. It is often used to replace flammable petroleum ether, ether, etc., and can be used as dental local anesthetic and refrigerant. and fire extinguishing agents. Dichloromethanes are usually used as their liquids as refrigerants. The solidification temperature of dichloromethane is -97℃, and the applicable temperature range is -50~-80℃. However, dichloromethane has the following obvious shortcomings: the liquid has high volatility and low boiling point, so the loss is very heavy, and the amount to be supplemented is very large; the chlorine element is very active, and it is easy to fall off to form hydrochloric acid and hydrochloride. Cause equipment corrosion; low water solubility, so it is easy to cause ice blockage and pipe burst damage to pipelines and equipment at low temperatures; low heat transfer coefficient, and the heat transfer coefficient of organic matter is low.

2. Calcium hydrogen phosphate with a large decrease is an inorganic substance, the chemical formula is CaHPO4, white monoclinic crystalline powder, odorless and tasteless, easily soluble in dilute hydrochloric acid, dilute nitric acid, acetic acid, slightly soluble in water (100 ℃ , 0.025%), insoluble in ethanol, usually in the form of dihydrate (CaHPO4 2H2O). Its dihydrate is stable in air, and when heated to 75 °C, it begins to lose crystal water and become anhydrous, and at high temperature, it becomes pyrophosphate. It is mainly used as a fortifier (calcium supplement) and a leavening agent. According to Chinese regulations, it can be used in biscuits and infant formula food with a maximum dosage of 1.0g/kg; it can also be used as a quality improver for fermented flour products, according to production needs. Use in moderation. As a food and feed additive, it can supplement phosphorus and calcium elements in livestock feed. It is used as a bulking agent in the food industry, used in biscuits and milk replacers, and the amount used is based on normal production needs. Also used as a yeast culture agent for bread making. Also used as a dough improver, nutritional supplements. It can be used as a feed additive to supplement phosphorus and calcium elements in poultry and livestock feed.
