Excellent chemical stability. It has the advantages of stable acid value, stable molecular weight, light color and good catalytic effect, and can completely replace potassium naphthenate. Solubility of solute is total solubility. This product is a universal sodium salt-forming agent for synthetic antibiotics by solubilization method. Compared with the traditional salt-forming agent sodium acetate, its obvious advantage is its mildness and stability after salt formation, and it can be soluble in many organic solvents, which is conducive to the separation of anhydrous final products and improves the quality and yield of products.<\/p>\n

Uses:<\/b><\/strong><\/p>\n

The role and use of n-butanol is a pharmaceutical excipient.<\/p>\n

Mainly used in the manufacture of phthalic acid, aliphatic dibasic acid and phosphoric acid n-butyl ester type plasticizers, they are widely used in a variety of plastics and rubber products, but also organic synthesis in the manufacture of butyraldehyde, butyric acid, butylamine and butyl lactate and other raw materials. They are also used as extractants for oils and fats, drugs (such as antibiotics, hormones and vitamins) and spices, additives for alkyd resin coatings, etc. They can also be used as solvents for organic dyes and printing inks, and dewaxing agents.<\/p>\n

Used in the production of butyl acetate, dibutyl phthalate and phosphoric acid plasticizers, also used in the production of melamine resin, acrylic acid, epoxy varnish, etc.; used as a chromatographic analysis reagent, also used in organic synthesis, etc.; used in the preparation of bananas, cream, whiskey and cheese and other types of edible flavors.<\/p>\n
