It is used as a raw material for the manufacturing of solvents, formaldehyde, methyl halide, methyl amine
, acetic acid, ethyl alcohol, acetic anhydride, DME and MTBE (methyl tertiary-butyl ether).
Additives that are commonly used include acetic acid, ammonium acetate, trifluoroacetic acid (TFA), methyl amine
Based on these experimental results, attention was focused on the SMA amic acid prepared from a styrene-maleic anhydride resin with a S/MA ratio of 1 (acid number of 475) and methyl amine
. The structure of this new resin, named 1000MA, and the properties of a typical water solution are given in Figure 4.
During studies of how two compounds -- methyl amine
, a somewhat fishy-smelling gas at room temperature, and diacetyl, which smells like butter -- react to form new flavor chemicals, Thomas H.
