Application

Methyldiethanolamine is used as an intermediate in the synthesis of numerous products. Its unique chemistry has resulted in its use in diverse areas, including coatings, textile lubricants, polishes, detergents, pesticides, personal-care products, pharmaceuticals, urethane catalysts, and water-treatment chemicals. Methyldiethanolamine is also used in gas treatment.

Dosage

Methyl Diethanolamine MDEA-based solvent designed for the selective removal of H2S from H2S and CO2 containing gas streams. The removal of sour or acid gas components such as hydrogen sulfide (H2S) or carbon dioxide (CO2) from gas streams is a common process, known as acid gas removal or gas sweetening. These impurities have to be eliminated or reduced to a specified level, for a variety of reasons: toxicity (H2S), corrosiveness of the gas, low caloric value, environment or other reasons depending on the application of the gas.

Inhalation:	Remove source of exposure or move person to fresh air and keep comfortable for breathing. If experiencing respiratory symptoms: Call a doctor
Eye Contact:	Direct contact with liquid or vapor will cause serious eye irritation. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for several minutes, while holding the eyelid(s) open. Neutral saline solution may be used as soon as it is available. Take care not to rinse contaminated water into the unaffected eye or onto face. If irritation persists, obtain medical attention
Skin Contact:	Take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Rinse/wash with lukewarm, gently flowing water and mild soap for 5 minutes or until product is removed. If skin irritation occurs or you feel unwell: Get medical advice/attention. Wash contaminated clothing before re-use or discard.
Ingestion:	Swallowing can cause irritation of the digestive tract with abdominal and chest pain, nausea, vomiting and diarrhea. Never give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. If vomiting occurs naturally, have victim lean forward to reduce risk of aspiration. Have victim rinse mouth with water again. Immediately obtain medical advice.
