The first step of the synthesis involves treatment of bisphenol A with sodium hydroxide, which deprotonates the hydroxyl groups of the bisphenol A. [6] (HOC 6 H 4) 2 CMe 2 + 2 NaOH → Na 2 (OC 6 H 4) 2 CMe 2 + 2 H 2 O. The diphenoxide (Na 2 (OC 6 H 4) 2 CMe 2) reacts with phosgene to give a chloroformate, which subsequently is attacked by ...

Professor Georges Jaubert invented the chemical compound Oxylithe in 1907. It was a form of sodium peroxide (Na 2 O 2) or sodium superoxide (NaO 2). As it absorbs carbon dioxide in a rebreather's scrubber it emits oxygen. This compound was first incorporated into a rebreather design by Captain S.S. Hall and Dr. O. Rees of the Royal Navy in 1909 ...

The first acrylic acid was created in 1843. Methacrylic acid, derived from acrylic acid, was formulated in 1865.The reaction between methacrylic acid and methanol results in the ester methyl methacrylate.
A common method for water softening involves the use of ion-exchange resins, which replace ions like Ca 2+ by twice the number of mono cations such as sodium or potassium ions. Washing soda (sodium carbonate, Na 2 CO 3) is easily obtained and has long been used as a water softener for domestic laundry, in conjunction with the usual soap or ...
