1、 Product introduction

Boron trichloride is a colorless fuming liquid or gas. Non combustible, with irritating and acidic smell. Dissolve in water to generate hydrogen chloride and boric acid, and release

A large amount of heat is hydrolyzed in wet air to generate smoke, which is decomposed into hydrochloric acid and borate in alcohol. Boron trichloride has strong reaction ability and can form

A variety of coordination compounds have high thermodynamic stability, but they will decompose to form low-cost boron chloride under the action of discharge. In the atmosphere, trichloride

Boron heating can react with glass and ceramics, and can also react with many organic substances to form various organoboron compounds.

2、 Technical indicators

3、 Packaging specification

Packaging can be provided according to customer requirements.

4、 Application of boron trichloride

It is mainly used for diffusion, doping and ion implantation in the manufacturing process of (silicon) semiconductor devices; Excellent catalyst in organic reaction;

It is used as the basic material for preparing organic boron compounds, and can also be used in the purification process of metal smelting such as aluminum, magnesium, zinc, copper alloys, etc.

5、 Precautions

Boron trichloride is of acute toxicity and high chemical reaction activity. It will explode when meeting water. With copper and its alloys, it may generate explosive

Sexual chloroacetylene. It is highly corrosive to most metals and can also corrode glass in case of moisture. White corrosion can be formed in humid air

Sexual dense smoke. It reacts violently with water and emits irritating and corrosive hydrogen chloride gas. Store in a cool and ventilated warehouse

Room. Keep away from kindling and heat source. The warehouse temperature should not exceed 50 ℃; It shall be stored separately from inflammable (combustible) materials and oxidants, and mixed storage is strictly prohibited. Storage

The area shall be equipped with leakage emergency treatment equipment. The operators must be specially trained and strictly abide by the operating procedures. Do not expose it to the sun, throw it heavily

It is strictly prohibited to bake cylinders with open fire and rough loading and unloading. There is a cylinder inspection time on the bottle neck of the cylinder, and the unqualified cylinder shall be entrusted to the Philippines

Lear special gas suppliers shall go to a qualified pressure vessel inspection unit for inspection. It is strictly prohibited to use expired cylinders.

6、 Leakage emergency treatment

Evacuate the personnel in the contaminated area quickly, isolate them for 150 meters, and strictly enter and exit the contaminated area. It is suggested that the emergency handling personnel should wear self-sufficiency

Positive pressure respirator, wear protective clothing. Cut off the source of leakage as much as possible. If it is gas, ventilate properly to accelerate diffusion. Dilute and dissolve with spray water.

Build a dike or dig a pit to collect a large amount of wastewater generated. If possible, the residual gas or leaked gas shall be sent to the water washing tower or the

Inside the fume hood. Leaking containers shall be properly treated and reused after repair and inspection. If it is liquid, absorb it with sand, vermiculite or other inert materials.

In case of a large amount of leakage, build a dike or dig a pit to receive it; Spray water cools and dilutes the steam, builds a dike or digs a pit to receive a large amount of wastewater.

Protect the on-site personnel, but do not spray water directly on the leakage point. Transfer to tank car or special collector with explosion-proof pump for recycling or transport to waste disposal

Site disposal.

7、 First aid measures

Skin contact: Take off the contaminated clothes immediately, and wash with plenty of flowing water for at least 15 minutes. Get medical attention.

Eye contact: immediately lift the eyelids and wash them thoroughly with a large amount of flowing water or normal saline for at least 15 minutes. Get medical attention.

Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, enter immediately

Perform artificial respiration. Get medical attention.

Ingestion: Rinse mouth with water and drink milk or egg white for those who take it by mistake. Get medical attention.

Fire extinguishing method: the product is incombustible. Cut off the air supply. Spray water to cool the container, and move the container from the fire site to an open place if possible.

Fire extinguishing agent: sand. Do not use water or foam to extinguish the fire.
