Highly concentrated aqueous solutions of N,N-dialkyl-glycines and process for preparation thereof
An aqueous high-concentration solution of N,N-dialkylglycine, economical, easy to handle, and useful for subsequent organic chemical reactions, is provided. Also is provided a process for production thereof. The aqueous high-concentration solution of N,N-dialkylglycine which contains the N,N-dialkylglycine at a concentration of 30–80% by mass, and a metal-mineral acid salt at a content of 0.3–3% by mass can be produced industrially from an aqueous N,N-dialkylglycine alkali metal salt as the source material by the steps of
