1-BUTOXY-2-PROPANOL

Propylene glycol butyl ether - Introduction

Propylene glycol monobutyl ether is an organic compound. The following is an introduction to the properties, uses, preparation and safety information about propylene glycol monobutyl ether:

Nature:

- Appearance: propylene glycol monobutyl ether is a colorless liquid with a special odor.

- Solubility: It can be dissolved in water, ethanol and ether solvents, but insoluble in non-polar solvents such as petroleum ether and aliphatic hydrocarbons.

- Stability: It is relatively stable at room temperature, but may burn when exposed to high temperatures, open flames or oxidants.

Purpose:

-propylene glycol monobutyl ether can be used as a solvent in organic synthesis, such as in fragrances, coatings, inks and plastics.

- It can also be used as detergents, dissolvers, irritants, etc.

Preparation:

The preparation of -propylene glycol monobutyl ether is generally obtained by the transesterification reaction of n-butanol and propylene glycol. The specific process is to heat N-butanol and propylene glycol ester under the action of catalyst to produce propylene glycol monobutyl ether and dehydration product (water).

- Reaction equation: N-butanol + propylene glycol ester → propylene glycol monobutyl ether + water

Packing : in 200kgs drum (can be based on customer's request)

Safety measure

Environmental hazard

Explosion hazard: This product is flammable and irritating.

Health hazard

This product belongs to low toxicity class. Harmful if inhaled, ingested or absorbed through the skin. It can irritate the skin. It has obvious irritation to the eyes and can cause conjunctivitis and keratitis. The heat decomposition releases irritating smoke.

First aid measure

Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water. Seek medical attention.

Eye contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.

Inhalation: Quickly remove from the scene to fresh air. Keep your airway clear. Administer oxygen if breathing is difficult. If breathing stops, give artificial respiration immediately. Seek medical attention.

Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.

Fire protection measures

Dangerous characteristics: flammable in case of open fire, high heat. It reacts with oxidizing agents. Decomposition by heat produces toxic fumes. In case of high heat, the pressure inside the container increases, and there is a risk of cracking and explosion.

Harmful combustion products: carbon monoxide, carbon dioxide.

Emergency treatment

Quickly evacuate the personnel from the contaminated area to the safety zone, isolate them, and strictly restrict access. Cut off the fire. Emergency personnel are advised to wear self-contained breathing apparatus and general work clothing. Do not contact spills directly. Cut off the source of leakage as much as possible. Prevent flowing into sewers, flood drains and other restricted Spaces. Small leakage: Absorb with sand. Large leakage: build a embankment or dig a pit to contain it. Transfer by pump to tank or special collector, recycling or transport to waste disposal site disposal.

Storage method

Operation precautions: closed operation, local exhaust. Prevents steam from leaking into the workplace air. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear a self-priming filter gas mask (half mask), chemical safety glasses, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Welding, cutting and other operations should not be carried out before removing liquid and vapor. Avoid creating smoke. Avoid contact with oxidants. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may have harmful residues.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. Keep out of direct sunlight. Keep the container sealed. Should be stored separately from oxidizer, do not mix storage. Equipped with the corresponding variety and quantity of fire equipment. The storage area should be equipped with leak emergency treatment equipment and suitable containment materials
