Anwendungen

Diethanolamine is used in the preparation of morpholine and diethanolamides, which is an active ingredient in cosmetics and shampoos. It acts as a surfactant and a corrosion inhibitor. It is utilized to remove hydrogen sulfide and carbon dioxide from natural gas. Further, it is an intermediate used in the rubber chemicals, as a humectant and a softening agent, and as an emulsifier and dispersing agent in agricultural chemicals. In addition to this, it is used in cutting oils, cleaners, soaps, polishers, and pharmaceuticals.

Bemerkungen

Hygroscopic and air sensitive. Incompatible with strong oxidizing agents, strong acids, copper, zinc, carbon dioxide and iron.

Boronic acids can be protected as cyclic boronates which are generally high-melting crystalline solids: J. Am. Chem. Soc., 77, 2491 (1955). NMR evidence has been presented indicating that derivatives of this type have a transannular B-N bond: J. Organomet. Chem., 246, 213 (1983):

For use in the modification of a boronic acid cleft in formation of a sodium-saccharide cotransporter, see: J. Org. Chem., 60, 2147 (1995). For use of the butyl cyclic boronate in the formation of a chiral dioxaborolane ligand, see: Org. Synth., 76, 86 (1998). See also Appendix 6.
