Some of yellow azo pigments have been synthesized by coupling of acetoacetarylide derivates with different substituted nitroaniline diazonium salts. The relationship between pigment structure and shade, m. p., and thermal stability, and the, effect of addition of surface active agent on coupling reaction product have been studied. TGA and differential thermal analysis in air of the pigments and the variance of visible spectra reflectance have also been determined.

The analysis in theory proves that cellular automaton is equal with a stochastic process that described by stochastic difference equations. The primary differential equation is expectation of this stochastic process. And its variance function is controllable. These results show that cellular automata are in agreement with primary differential equation in the statistical sense.
