CHARACTER

cyclohexene is a colorless transparent liquid, chemical formula C6H10, molecular weight 82.14. It is mainly used in organic synthesis, oil extraction and as a solvent. Cyclohexene has an active double bond and can react with other compounds, so it plays an important role in the production of fine chemicals such as medicine, pesticide and dye. In addition, it is also soluble in ethanol, ether and other organic solvents, insoluble in water. Cyclohexene has stable physical properties, low melting point and boiling point, easy storage and transportation, and has a wide range of applications in the chemical industry.

APPLICATIONS

(1) Synthetic resin: Cyclohexene is an important raw material for the synthesis of a variety of resins, which are widely used in coatings, paints, adhesives and other fields. Through different synthesis methods, resins with different performance characteristics can be obtained to meet the needs of different industries.

(2) Production of nylon: Cyclohexene is one of the key raw materials for nylon production. Through polymerization, high molecular weight nylon molecular chains can be obtained to prepare nylon products with excellent performance. These products are widely used in clothing, shoes, hats, bags and other fields.

(3) Preparation of spices and dyes: Cyclohexene can be used to prepare various spices and dyes, providing rich and colorful raw materials for cosmetics, food, textile and other industries. These fragrances and dyes not only have a beautiful smell and color, but also have good stability and safety.

(4) Used as solvent and extractant: cyclohexene is insoluble in water, but miscible in ethanol, ether and other organic solvents, so it is often used as solvent and oil extractant in organic synthesis.

(5) Other applications: Cyclohexene can also be used for the synthesis of lysine, cyclohexanone, phenol, polycyclic olefin resin, chlorocyclohexane, rubber additives, cyclohexanol, etc., and is commonly used as a catalyst, high octane gasoline stabilizer, etc. It is also widely used in the production of pharmaceuticals, pesticides, detergents, explosives, feed additives, polyesters and other fine chemicals.

cyclohexene -properties

Colorless flammable liquid, insoluble in water, soluble in ether. Relative density 0.81096. Melting point -103.5 ℃. Boiling point 83 ℃. Flash point -11. 67 ℃. Aniline number 10. Refractive index 1. 44654.

Cyclohexene -preparation

from cyclohexanol in the presence of catalyst sulfuric acid, heating to generate cyclohexene, distillation to obtain crude products. It is then washed with a saturated solution of refined salt, and then neutralized with a trace amount of acid by sodium sulfate solution. After washing with water, layering, drying, filtering and rectifying, the fraction at 82-85 ℃ is collected to obtain the finished cyclohexene.

Cyclohexene -Uses

This product is an organic synthetic raw material, such as the synthesis of lysine, cyclohexanone and phenol, but also can be used as a catalyst solvent and petroleum extractant.

Cyclohexene -Safety

This product has moderate toxicity, its toxic effect is basically similar to cyclohexane, when splashed and skin, because of its rapid evaporation caused by irritation. When inhaled into the human body, there is an anesthetic effect. In warm-blooded animals, anesthesia is fast, but does not cause intermittent spasms or shivers, which can reduce blood pressure and pulse and respiration. The maximum allowable concentration in the air is l015mg/m3. The production site shall be well ventilated and the operators shall wear protective equipment.
This product is packed in glass bottles, each weighing 20kg, and is packed in wooden cases. Store at room temperature. This product is flammable, the fire source should be isolated during storage and transportation to avoid collision.

Cyclohexene -Introduction

cyclohexene is a colorless liquid with a special aromatic odor. Cyclohexene is an unstable compound that readily oxidizes and polymerizes in air.

cyclohexene has a wide range of uses. Cyclohexene can also be used as a reaction agent for various chemical reactions in organic synthesis. There are various methods for preparing cyclohexene

. A common method is the hydrogenation of a six-carbon ring to cyclohexane, followed by a dehydrogenation reaction to obtain cyclohexene. In addition, it can also be obtained by a method such as intermolecular Clausen condensation reaction, dehydration and dehydrogenation of olefins.

cyclohexene is flammable under certain conditions and may burn under open flame or high temperature. It also has a certain carcinogenic and irritant, should avoid contact with the skin, inhalation of gas or eating. In the use or storage of cyclohexene, pay attention to take appropriate safety measures, such as wearing protective gloves, masks and so on.
