Biodegradable aspartic acid polymers for preventing scale formation in boilers

摘要

A biodegradable anti-scalant for steam generators, boilers and other heat transfer equipment is provided. Anti-scalants prepared in accordance with the present invention include aspartic acid, poly(aspartic acid) and copolymers of aspartic acid and functionalized aspartic acid. Anti-scalants provided in accordance with the present invention are biodegradable and therefore more environmentally friendly than currently available anti-scalant for use with hard water. Methods and use of making anti-scalants are also provided.
