Features: Contains two hydroxyl groups and one amino group. Hydroxyl reduces the vapor pressure, increases the solubility, is conducive to the absorption of acid gas, and can increase the concentration, reduce circulation, and reduce energy consumption. The presence of the methyl group in the amino group reduces the alkalinity and activity of the amino group and reduces the CO2 absorption rate.

Antioxidants are substances that block the adverse effects of oxygen. It is a class of substances that can help capture and neutralize free radicals, thereby eliminating the damage caused by free radicals to the human body.
Antioxidants refer to food additives that can prevent or delay the oxidation of food, improve the stability of food and prolong the storage period. The correct use of antioxidants can not only prolong the storage period and shelf life of food, bring good economic benefits to producers and consumers, but also bring better food safety to consumers.
Antioxidants can be used as hydrogen donors to scavenge free radicals generated during the chain initiation stage, thereby inhibiting or reducing the oxidation of oils. Therefore, in order to delay the oxidation of fats and extend their shelf life, the most common and effective way is to add antioxidants to the fats.
Acetic acid, commonly known as acetic acid (AcOH) because it is the main component of vinegar, is one of the most important fatty acids. In nature, it occurs in many plants as free or esters. Molecular formula CH3COOH.
Antifoaming agent refers to a substance that can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce or eliminate the original foam. In the papermaking process, due to unreasonable sizing, poorly washed pulp, alkaline fillers used in acid systems, and various additives, foams will accumulate in the wet end of the papermaking system, resulting in the formation of foam dots on the paper.
Titanium dioxide naturally exists in titanium ores such as titanium ore and rutile. Its molecular structure gives it high brightness and covering properties, but it must first be chemically extracted and purified. More than 60 years ago, DuPont invented the chlorinated titanium dioxide production process. Compared with the old sulfuric acid process, it can manufacture high-quality pigment products while reducing environmental emissions and Chemicalbook energy consumption.
Water retaining agent (for bread, cake); Carrier solvent (for spices, pigments, water-insoluble preservatives, etc.); Thickener (used for beverages, liquor preparation, etc.) Plasticizer (candy, dessert Chemicalbook, meat products); Sweeteners. EEC regulations can be used for alcoholic beverages, candies, cakes, coating glazing, meat and cheese coating, non-alcoholic beverages, baked products, gum, gelatin sweets, etc.
Oxygen is a colorless and odorless gas. It is not easily soluble in water. It has a density greater than air and supports combustion.
Comb grass is a characteristic plant that can be grown all over China. The oil processed from the seeds of comb grass is comb grass. Glycine max is a special medicine made from oil, which has extremely high medicinal value.
About 78% of nitrogen gas can be used to make ammonia, nitric acid, nitrate, cyanide, etc. When making explosives; filling high-temperature thermometers and incandescent bulbs; forming inert material preservation materials for drying boxes or glove bags.
