General Description

Pigment Yellow 6 is a synthetic organic pigment that is commonly used in plastic, printing inks, and paints. It is a bright and opaque yellow colorant with good lightfastness and heat stability, making it suitable for outdoor applications. The chemical composition of Pigment Yellow 6 includes lead chromate, which provides its vibrant hue. However, due to concerns about the toxicity of lead, there are restrictions on the use of this pigment in some regions. Overall, Pigment Yellow 6 is a versatile and durable pigment with a wide range of industrial applications.

Method used for synthesizing azo compound using solid particle one kettle method

The invention relates to a method used for synthesizing an azo compound using solid particle one kettle method. The method comprises following steps: solid particles are introduced into a reaction container, an inorganic acid, an aromatic primary amine, sodium nitrite, water, and a coupling component are added, mechanism stirring is carried out, when the reaction is monitored to be finished, filtering and rinsing are carried out, and the obtained filter cake is a finished product; or the solid particles are introduced into the reaction container, the inorganic acid, the aromatic primary amine,sodium nitrite, and water are added, mechanical stirring is carried out, after complete conversion of the aromatic primary amine, the coupling component is added, mechanical stirring is carried out,when the reaction is monitored to be finished, filtering and rinsing are carried out, and the obtained filter cake is a finished product. The solid particles are preferably selected from polytetrafluoroethylene particles, haw seeds, or stainless steel sand. The solid particles are added into the reaction system to promote reaction, no pre-heating or alkali adding dissolving of diazo components orthe coupling component is needed; most reaction is finished in 1h; reaction time is short; product quality is high; and reaction filtrate and excess inorganic acid can be recycled for a plurality of times.
