Acid functionalized carbons as catalyst for glycerol etherification with benzyl alcohol [PDF]

open access: yes, 2021
In this paper, the catalytic behaviour of two different carbonaceous systems, commercial carbon (Cc) and synthetic carbon (Cs) functionalized with concentrated sulfuric acid (–SO₃H) and with reduced aryl diazonium salt (–PhSO₃H), was studied in the ...

Reaction Rate of Methanesulfonic Acid (MSA) Solutions with Calcite Using a Rotating Disk Apparatus [PDF]

open access: yes, 2016
Methanesulfonic acid (MSA) has been proven as a scale remover and, more recently, as a stand-alone stimulation fluid in carbonate acidizing. MSA is a strong alkyl sulfonic acid having a pK value of -1.9, and it dissolves carbonate and oxides with its ...
