标 题:Methods for triazole synthesis
发明人：HENDERSON WILLIAM H; RICHARDSON JOHN
权利人:CHEMTREAT INC
摘要:Disclosed are methods of synthesizing triazoles that avoids the use of concentrated acids in favor of carbonic acid generated from CO 2 that can be practiced at ambient and/or elevated temperature and/or atmospheric and/or elevated pressures. The disclosed methods also provide a way of synthesizing triazole products that are sufficiently pure and/or of sufficient concentration whereby the reaction product(s) may not require purification or other treatment before being used in, for example, formulating water treatment compositions that will tend to suppress corrosion or as an intermediate product in a more complex synthesis.
