Specification

The CAS registry number of N-Methyldiethanolamine is 105-59-9. Its EINECS registry number is 203-312-7. The IUPAC name is 2-[2-hydroxyethyl(methyl)amino]ethanol. In addition, the molecular formula is C₅H₁₃NO₂. What's more, it is a colourless viscous liquid and soluble in water. It is mainly used as emulsifier and acid gas absorbent, pH control agents, polyurethane foam catalyst. Besides, it is also used as an intermediate for hydrochloric acid chlormethine which is one of anticancer drugs.

Physical properties about this chemical are: (1)ACD/LogP: -0.72; (2)ACD/LogD (pH 5.5): -3.49; (3)ACD/LogD (pH 7.4): -1.89; (4)ACD/BCF (pH 5.5): 1; (5)ACD/BCF (pH 7.4): 1; (6)ACD/KOC (pH 5.5): 1; (7)ACD/KOC (pH 7.4): 1; (8)#H bond acceptors: 3; (9)#H bond donors: 2; (10)#Freely Rotating Bonds: 6; (11)Polar Surface Area: 21.7 Å²; (12)Index of Refraction: 1.476; (13)Molar Refractivity: 32 cm³; (14)Molar Volume: 113.3 cm³; (15)Polarizability: 12.68 ×10^-24cm³; (16)Surface Tension: 43 dyne/cm; (17)Density: 1.051 g/cm³; (18)Flash Point: 126.7 °C; (19)Enthalpy of Vaporization: 56.25 kJ/mol; (20)Boiling Point: 247 °C at 760 mmHg; (21)Vapour Pressure: 0.00431 mmHg at 25°C.

Preparation of N-Methyldiethanolamine: it can be prepared by methanal and diethanolamine. Add methanoic acid into the reactor and heat it to boiling at first. Then add methanal and diethanolamine with stirring in 1 hour. The reaction temperature should be maintained at 90-98 °C. In addition, the reaction should reflux for 4 hours. At last, you should collect 120-130 °C(0.53 kPa) fractions through vacuum distillation.

N-Methyldiethanolamine can be prepared by methanal and diethanolamine.

Uses of N-Methyldiethanolamine: it can be used to get 4-methyl-morpholin-2-one. This reaction will need reagents RuH₂(PPh₃)₄ and acetone, and solvent toluene. The reaction time is 3 hours at reaction temperature of 180 °C. The yield is about 95%.

N-Methyldiethanolamine can be used to get 4-methyl-morpholin-2-one
