/ˈsɔlveɪ/,

/ˈsɑlveɪ/

Etymology: < the name of Ernest Solvay (1838–1922), Belgian chemist, who developed the process.

Chemistry.

Solvay (or †Solvay's) process: a method of making sodium carbonate using brine, ammonia, and carbon dioxide (which is usually made as part of the process, by calcining limestone); also called ammonia-soda process. Hence Solvay plant, etc.
