product details

BRIEF DESCRIPTION

Perfluorobutyric acid, also known as heptafluorobutyric acid, is a colorless liquid at room temperature, smells like butyric acid, and is highly acidic. Perfluorobutyric acid is stable in nature and can undergo salt formation reactions, esterification reactions, substitution reactions, dehydration reactions and reduction reactions of alcoholic hydroxyl groups. Perfluorobutyric acid can be regarded as a product in which all hydrogen atoms in the butyric acid molecule are replaced by fluorine atoms. Industrially, perfluorobutyric acid is prepared by electrochemical fluorination, using butyryl chloride as the starting material, and without Water hydrogen fluoride undergoes electrolytic fluorination reaction, and the anode product is neutralized and acidified to obtain the product.

USE

1. Heptafluorobutyric acid is mainly used as a raw material for special coatings, polymers and surfactants in the chemical industry.

2. It can be used to prepare compounds such as fluorocarbons and fluorinated acrylates.

3. Heptafluorobutyric acid can also be used as an etchant, cleaning agent and lubricant in the electronics industry.

4. Used as catalyst, activator, acidifier, intermediate for insecticides and fungicides, esters, and also used in synthetic rubber.

STORAGE CONDITIONS

1. Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Special personnel for safekeeping.

2. Keep container sealed. Protect from moisture and rain. Should be used with alkalis, oxidants, edible chemical raw materials, and wet items

Store separately.

3. Load and unload with care when handling to prevent damage to packaging and containers. Smoking, drinking, and eating are not allowed at the operation site. Packing and moving

Pay attention to personal protection when operating.

PACKAGE

Ordinary wooden boxes outside screw-top glass bottles, iron-cap pressure-top glass bottles, plastic bottles or metal barrels (cans); outside full-floor grate boxes or fiberboard boxes outside thread-top glass bottles, plastic bottles or tin-plated thin steel barrels (cans) Or plywood boxes.

CHEMICAL PROPERTIES

1. Heptafluorobutyric acid is a colorless to light yellow liquid with a special pungent odor.

2. It is a highly volatile substance, about 16 times more volatile than water. Due to its high volatility, you need to pay attention to protection when in contact with it.

3. Heptafluorobutyric acid is a strong acid and highly corrosive, so please pay attention to safety during operation.
