名称:三甲基碘硅烷
 

纯度:99% 包装:240kg/桶

结构式
   

CAS:  16029-98-4
分子式:  C3H9ISi
分子量:  200.09

中文名称:  三甲基碘硅烷
                   碘代三甲硅烷
                   三甲基硅基化碘

英文名称:  Trimethylsilyl iodide
                    iodotrimethyl-silane
                    iodotrimethylsilane
                    trimethyliodosilane
                    trimethyliodosilane(tmis)
                    iodo-trimethyl-silane

性质描述:  可燃液体。沸点106-108℃,相对密度(20/4℃)1.41。

用途:   主要用于脱烷基化及相关反应中的一种高效试剂,可作为一些活性基团(氨基、羟基)的保护剂,可用于头孢的合成。

使用注意:储存中易变红(主要是分解出单质碘),因此在储存中加入铜粉。在空气中易发烟,且使溶液发红(原因 与水反应).

Section 3 - Hazards Identification

 
EMERGENCY OVERVIEW
Appearance: clear very slight brown liquid. Flash Point: -31 deg C.
Danger! Water-reactive. Causes eye and skin burns. Causes digestive and respiratory tract burns. Flammable liquid and vapor.
Target Organs: None known.

Potential Health Effects
Eye: Causes eye burns.
Skin: Causes skin burns.
Ingestion: Causes gastrointestinal tract burns.
Inhalation: Causes chemical burns to the respiratory tract. Aspiration may cause respiratory swelling and pneumonitis.
Chronic: Not available. None

Section 4 - First Aid Measures


Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: Containers can build up pressure if exposed to heat and/or fire. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors can travel to a source of ignition and flash back. Flammable liquid and vapor. Reacts with water to form explosive hydrogen gas.
Extinguishing Media: Use carbon dioxide or dry chemical. DO NOT USE WATER!
Flash Point: -31 deg C ( -23.80 deg F)
Autoignition Temperature: Not available.
Explosion Limits, Lower: Not available.
Upper: Not available.
NFPA Rating: Not published.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition. Use a spark-proof tool.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Use only in a well-ventilated area. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Do not ingest or inhale. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Keep under a nitrogen blanket. Store in a cool, dry, well-ventilated area away from incompatible substances.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
