Main article: Tertiary amine
Trimethylamine has typical properties of tertiary amines, including salt formation, oxidation, and no reaction in the Hisberg reaction of trimethylamine.
Application:
The gas sensor for detecting fish freshness is realized by detecting trimethylamine. [1] It can be used as a nucleophile in organic synthesis. Alarms, analytical reagents and organic synthesis raw materials for the preparation of disinfectants and natural gas. [1] Preparation of medicines, pesticides, photo materials, rubber auxiliaries, explosives, chemical fiber solvents, strongly basic anion exchange resins, dye leveling agents, surfactants and basic dyes.
Protective measures:
Respiratory protection: When the concentration in the air exceeds the standard, wear a filter gas mask (half mask). In emergency rescue or evacuation, it is recommended to wear oxygen breathing apparatus or air breathing apparatus.
Eye Protection: Wear chemical safety goggles.
Body Protection: Wear anti-static overalls.
Hand Protection: Wear rubber gloves.
Others: Smoking, eating and drinking are strictly prohibited at the work site. After work, take a shower and change clothes.
First aid measures:
Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water for at least 15 minutes. 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 leave the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration and seek medical attention immediately.
Uses:
1. Used as disinfectants, natural gas alarms, analytical reagents and raw materials for organic synthesis, as well as raw materials for medicine, pesticides, photographic materials, rubber auxiliaries, explosives, chemical fiber solvents, surfactants and dyes. The reaction product with ethylene oxide is used as a catalyst for the polycondensation reaction. The reaction product choline chloride with 2-chloroethanol is used as an additive in chicken feed.
2. Main organic synthetic raw materials, can be used to produce various industrial auxiliaries, surfactants and dyes, ion exchange resins, flocculants, other cationic polymers, etc.
3. Used as analytical reagent and for organic synthesis, also used as disinfectant, etc.
