Tetrahydrothiophene Industrial Grade

Four thiophene thiophene is mainly used as city gas, natural gas and other gas fuel deodorant, that is warning agent. It can also be used as raw material for the production of pharmaceuticals, pesticides and light chemicals. At present, in accordance with international standards requirements, urban gas, natural gas and other gas deodorant must use four thiophene thiophene, banned the original use of ethyl mercaptan and other deodorant. At present, the domestic market required four hydrogen thiophene is about 400 tons / year, mainly rely on imports, is expected to "fifteen" plan at the end of the market demand will reach 1600 tons / year or more,

application

Application: used as solvent and organic synthesis intermediate.

Fire fighting measures

Risk characteristics: high temperature, open flame and strong oxidizing agent are easy to cause combustion.

Harmful combustion products: carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur oxides.

Fire extinguishing method: spray cooling containers and, if possible, move containers from the fire to the open spaces. Foam, carbon dioxide, dry powder, sand.

Leakage treatment

Emergency treatment: quickly evacuate the personnel from the contaminated area to the safe area, and isolate and strictly restrict access. Cut off fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear protective clothing. Cut off the leak as much as possible. To prevent the inflow of sewage, flood channel limited space. Small amount of leakage: absorbed by activated carbon or other inert materials. It can also be scrubbed with an emulsion made of nonflammable dispersants and diluted with the liquid into the waste water system. A large leak: construct a barrierpit to contain. Foam mulch to reduce steam damage. Transfer to tank car or special collector with explosion proof pump, recycle or transport to waste disposal site.

Operation storage

Points for attention: closed operation, partial air exhaust. Operators must undergo special training and strictly follow the operating procedures. It is recommended that operators wear self - filtered gas masks (semi - masks), safety goggles, poison penetration suits and rubber - oil gloves. Keep away from fire, heat, smoking in workplaces. Use explosion-proof ventilation systems and equipment. Prevent steam from leaking into the air in the workplace. Avoid contact with oxidants. When filling, the flow rate shall be controlled, and the grounding device shall be used to prevent the accumulation of static electricity. Remove light and light when handling and prevent packing and container damage. Equipped with the corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.

Storage: store in a cool and airy warehouse. Keep away from fire and heat. The temperature should not exceed 30 DEG C. Keep the container sealed. Should be stored separately with oxidants, shall not be mixed storage. Adopt explosion-proof lighting and ventilation facilities. The use of mechanical equipment and tools for sparking is prohibited. The storage area shall be equipped with emergency disposal equipment and suitable storage materials.
