    Pharmaceutical and Chemical Intermediates 1: Diabetic Intermediates Xylitol

    Xylitol, also known as pentyl pentanol, usually appears as a white crystalline powder with a melting point below 100 degrees Celsius. It is chemically stable and soluble in water, and is a polyol with a sweetener, a therapeutic agent and a nutrient. Xylitol has a wide range of functions and is particularly popular with people with diabetes. It not only satisfies the dependence of diabetics on sweetness, but also has the effect of protecting the liver from the growth of oral bacteria. The most familiar thing in life is the chewing gum made from xylitol. In fact, its application is not limited to food, but is widely used in medicine, paint, leather and other fields. At present, the demand for xylitol is increasing, and it has broad market prospects.

    Pharmaceutical Chemical Intermediate 2: Vitamin Drug Intermediates Sorbitol

    In recent years, there are many kinds of vitamin products on the market, among which vitamin A, vitamin B, vitamin C and vitamin E are very popular. Almost every hospital is an indispensable standing medicine. Among them, vitamin C is the leader in common vitamins, and sorbitol, which is the raw material for its production, is particularly attractive. The production cost of sorbitol is relatively high, and since domestic production is often insufficient, it is often required to be imported from abroad. Sorbitol is widely used in the food industry, and we can see its name in the production ingredients of many food packaging belts. It is usually used as a water control agent in the process of making toothpaste, tobacco, ink, and the like.

    Pharmaceutical intermediates III: furan and its derivatives

    Furan, also known as oxalate, is a colorless, transparent liquid with a chloroform odor. Furan has a low melting point, is insoluble in water, and is easily soluble in organic solvents. It has volatile and flammable properties. It is commonly used in the preparation of decarboxylation of carboxylic acid with water and decarbonylation of furfural. The catalysts required for preparation include aluminum silicate, metal oxides and the like. The preparation temperature was 400 degrees Celsius. The main raw materials for scorpion drugs are sultanate (also known as chlorhexidine), sulphonate, sulphonic acid and propylpyramine. In addition, furan is also a synthetic raw material for various other organic compounds, such as tetrahydrofuran, furanamide and the like. Therefore, in general, furan is a good product with a good development prospect.
