MSA LC
FOR BIODIESEL
Methane Sulfonic Acid
–
Low Corrosion
The Advanced Acid Catalyst in Biodiesel Manufacturing
Arkema, in keeping with its quest for
innovation that serves customers, introduces
to the biodiesel industry MSA LC, a low
corrosion version of its methane sulfonic
acid (MSA). It provides the following
outstanding benefits:
•High yields of quality biodiesel (fatty acid methyl esters or FAME) via enhanced
selectivity
•Corrosion reduction in the whole process
if used as illustrated below
•Reduction of waste streams
•Versatile acid in biodiesel manufacture for catalysis, acidulation and neutralization
MSA LC is equally effective on feedstocks
containing 2% to >10% free fatty acid (FFA)
content. Typical protocols followed are:
•If FFA >2%; biodiesel producers usually
carry out the pre-treatment step transforming
FFA to FAME by esterification in the
presence of methanol and MSA LC.
The intermediate mixture then undergoes
an alkali-catalyzed transesterification
reaction to produce FAME.
•If FFA <2%; MSA LC is used to acidify
the glycerol phase obtained after
transesterification to convert soaps
(FFA salts) back to FFA. This FFA can
then be esterified using MSA LC and
methanol to produce additional FAME.

MSA LC is an exceptional acid that has the
same well known performance properties as
commercially available MSA but with significantly
reduced corrosivity towards 304L and 316L
stainless steels.
Arkema looks to build strong relationships with
a select group of versatile global biodiesel
producers using a diverse range of feedstocks.
Arkema believes these producers will observe
the following advantages when using
MSA LC to produce biodiesel:
•Higher conversion yield and better selectivity
•Better color and clarity
•Flexibility to use diverse feedstocks with
a wider range of FFA content
•Greater financial benefits of using cheaper
“high FFA content” feedstock
•Significant corrosion reduction in primary
and secondary process units
•Elimination/reduction in waste treatment.
MSA LC and its salts are completely
biodegradable with low COD
