                  Further information than is given in BIOS Final Rept. 478 on the manufacture of Mersol-type detergent products from a hydrogenated Fischer-Tropsch cut of boiling range 220°-320°, Mepasin.  Mersol H2 is produced by the action of SO2 and Cl on Mepasin.  Mersol H2 can be converted to Mersolat by reacting with caustic soda in 10% solution.  Hostapon is produced by the direct action of SO2 and O2 on Mepasin, using light or acetic anhydride as catalyst.  The detergent properties of Hostapon are essentially the same as Mersolat.  Gives details of methods.
