tert-Butyl methyl ether

Description：

Methyl tert-butyl ether (MTBE), is an organic compound, chemical formula C5H12O, colorless transparent liquid, insoluble in water, soluble in ethanol, ether, is an excellent high octane gasoline additive and antiknock agent.

Nature:

- Appearance: Colorless liquid

- Solubility: Soluble in water, alcohol and ether solvents

- Melting point: -110 °C

- Boiling point: 55-56°C(lit.)

- Density: 0.7404

Purpose:

- Neutral solvent: methyl tert-butyl ether is often used as a neutral solvent in the chemical industry and can dissolve many organic compounds.

- Gasoline additives: methyl tert-butyl ether is added to gasoline, which can improve combustion efficiency and knock resistance, help reduce exhaust emissions, and improve the impact resistance of gasoline.

Chemical intermediates: MTBE is also an intermediate product of many chemical reactions and can be used to synthesize other organic compounds.

Preparation:

Methyl tert-butyl ether is commonly prepared by the reaction of isobutylene with methanol. The reaction equation is as follows:

C4H8 + CH3OH → C5H12O

Safety information:

- Methyl tert-butyl ether is flammable, should avoid contact with open flame or high temperature substances, and stored in a cool and ventilated place.

- Avoid inhaling methyl tert-butyl ether vapor and avoid contact with skin and eyes.

Methyl tert-butyl ether may have a negative impact on the environment, so the relevant provisions of environmental protection should be observed when used and handled.

- During industrial production, appropriate safety measures should be taken, including the wearing of personal protective equipment such as protective glasses, respirators and protective gloves.

Packing :

150kg/Iron drum , 80DRUMS/12MT/20'GP

Application:

MTBE used as a gasoline additive to increase the octane number, and can also be cracked to produce isobutylene, used as a gasoline additive, with excellent anti-knock properties. 

It has good miscibility with gasoline, little water absorption and no pollution to the environment. 

As a raw material for organic synthesis, high-purity isobutylene can be produced.

It has a mild anesthetic effect in medical application.

N-hexane is an organic solvent, has good viscosity, often used in rubber food, pharmaceutical, perfume, shoemaking, tape, ball making, grinding (grinding), leather, textile, furniture, paint industry, or for dilution, or cleaning solvents, or adhesive. In addition, it can be used as a solvent in the extraction of seed oil (such as soybean oil, cottonseed oil, flax oil, peanut, safflower oil, etc.); It can also be used as raw material for the manufacture of polymers; Such as polypropylene (polypropylene), polyethylene (polyethylene)

Environmental impact:

N-hexane is a common solvent and additive that plays a role in a variety of industrial applications. However, its widespread use also poses potential environmental risks, as it can be released into the environment through various waste streams. As a component of natural gas and crude oil, the release of n-hexane can have adverse effects on ecosystems.

At room temperature of 25°C, n-hexane has a vapor pressure of 153 mmHg, indicating that it exists primarily as steam in the atmosphere. This vapor form of n-hexane reacts with photochemically produced hydroxyl radicals in the atmosphere and gradually degrades, with a half-life of about 24 hours in the air. N-hexane does not contain photochromophores that can be absorbed at wavelengths greater than 290nm, so it is unlikely to be subjected to direct photolysis by sunlight.
