Applications

1、Pesticide Synthesis：Insecticide (Buprofezin), Herbicide (Mefenacet).

2、Dye Synthesis: Cationic Brilliant Red FG, Cationic Pink B, Reactive Yellow Brown KGR.3、Gasoline Additive: Increases gasoline octane number. Free of lead, iron, manganese, sulfur, and other restricted elements/oxygenates in gasoline. Suitable for blending various gasolines. Direct addition ensures convenient, stable, and reliable mixing.

N-Methylaniline Additive Effectiveness:

Significantly improves octane number.

Sensitivity varies across different gasolines, but follows trends:

A: Low-octane gasoline > High-octane gasoline

B: Straight-run gasoline > Catalytic gasoline > Reforming gasoline > Alkylate > Coking gasoline

C: Paraffinic base > Naphthenic base

Recommendation: Users should test different additive quantities for specific oil types before blending to achieve target values.
