Properties of butyl methacrylate nitrile

Butyl methacrylate acrylonitrile (BMA) is an important chemical raw material. Its chemical formula is C9H13NO2 and its molecular weight is 167.2. The compound has obvious volatility and low water solubility, appears as a colorless transparent liquid, and has a strong pungent odor. BMA has a boiling point of about 157°C, a melting point of -64°C and a flash point of 49°C. It has a density of about 0.89g/cm³(20°C) and a viscosity of 0.95 mPa · s(20°C). These properties make BMA relatively stable at room temperature, but may decompose at high temperatures or under exposure to strong oxidants.

Use of butyl methacrylate nitrile

BMA is widely used in a variety of industrial fields, including:

1. coating industry: BMA is used to prepare acrylate coatings with excellent adhesion, gloss and weather resistance, making the coating more durable and suitable for automotive coatings, architectural coatings and industrial coatings.
2. Adhesive its application in the field of adhesives is equally important. The chemical structure of BMA gives adhesives good heat resistance and water resistance, and is widely used in packaging, wood, paper and other industries.
3. Plastic and resin: BMA can be copolymerized with other monomers to prepare various functional resins and plastics, such as copolymers can be used as thermoplastics, optical resins and other materials.
4. textile treatment: In textile finishing, BMA can improve the abrasion resistance and stain resistance of fabrics, and improve the hand feeling and appearance.
5. Other areas due to its special chemical properties, BMA can also be used to prepare chemical products such as plasticizers and surfactants.

Upstream Raw Material Analysis

the production of butyl methacrylate nitrile mainly depends on the following upstream raw materials:

1. methacrylic acid: This is one of the main raw materials of BMA, which is made by the reaction of propylene and formaldehyde through hydroxyl methylation. Methacrylic acid is an important acrylic acid derivative that is widely used in the preparation of various polymers.
2. Butanol butanol is an important intermediate in the production of BMA by esterification with methacrylic acid to produce butyl methacrylate. Butanol can be obtained from ethylene or butene by hydroxylation.
3. Cyanide: Such as hydrogen cyanide, used to provide cyano (-CN), introduced into the molecular structure by cyanation reaction.

Downstream Product Analysis

BMA's downstream products are mainly concentrated in the following areas:

1. coatings and paints as an important coating monomer, BMA is used to produce high-performance acrylate coatings, which are widely used in the fields of automobile, construction and industrial protection.
2. Adhesives and sealants: The copolymer prepared by BMA has good adhesion and durability, and is widely used in the bonding and sealing of construction, automobile, electronics and other fields.
3. Textile auxiliaries textile auxiliaries prepared by BMA can endow fabrics with excellent physical and chemical properties and improve the added value of products.
4. polymer material: BMA and other monomers, the preparation of polymer materials used in electronics, medical, packaging and other high-tech fields, has broad market prospects.

Production process and technical analysis

the production process of butyl methacrylate nitrile mainly includes the following steps:

1. raw material preparation: First prepare raw materials such as methacrylic acid, butanol and hydrogen cyanide to ensure that their purity and quality meet production requirements.
2. esterification reaction methacrylic acid and butanol are esterified under the action of a catalyst to produce butyl methacrylate.
3. cyano reaction: The resulting butyl methacrylate and hydrogen cyanide are cyanated to introduce cyano groups to produce butyl methacrylate nitrile.
4. refining and purification the product is refined and purified by distillation, extraction and other processes to remove impurities and obtain high-purity BMA products.

Storage and transportation methods

because butyl methacrylate nitrile has a certain volatility and toxicity, its storage and transportation require special attention:

1. storage Environment: BMA should be stored in a cool, well-ventilated warehouse, away from direct sunlight and high temperature environment. The storage container shall be closed and leak-proof, usually stainless steel or high-density polyethylene containers.
2. Fire Prevention Measures: Due to its low flash point, BMA is a flammable liquid. The warehouse should be equipped with corresponding fire prevention facilities. It is forbidden to approach open flames and heat sources.
3. Leakage prevention measures leakage emergency treatment equipment shall be set in the storage area to prevent environmental pollution and safety accidents caused by leakage.
4. Transportation requirements: Special vehicles that meet the specifications should be used during transportation to ensure that the container is sealed to prevent collision and vibration. The transportation route should avoid residential areas and environmentally sensitive areas, and strictly abide by the relevant laws and regulations for chemical transportation.
