The main purpose of N-methylanihe formation of required proknock properties of gasong its production. Moreover, the octane and ecological compatibility of the product are regulated by MMA. These two factors have made N-methyl aniof the most popular multifunctional additives. Composition of N-methylanisubstance is replaced aromatic amine. N-methylanintages Use of additives of this kind has a of advantages: In comparison with other octane-increasing additives MMA is required seven times less, what allows to cut down transportation costs and to increase competitiveness; 1% of the additive of total amount increases the octane from 8 to 10 units, depending on the initial product At the correct use of monomethylaniium-95 gasoch properties satisfy with all existing state standards; The product allows to reduce of harmful emissions to the atmosre at combustion, reduces consumption of fuel by 5-6%; With the additive addition gasomes more stable, so, a user will choose it.
