1,3-Benzodioxole-2-carboxamide, N,N-diethyl- - Introduction
Pigment Permanent Red F5RK is an organic Pigment with the chemical name of lead 4-amino -2, 5-dimethoxybenzenesulfonate and the molecular formula of C14H16N2O5S2Pb. It is a dark red or pink pigment with good vividness and gloss.
pigmentperred F5RK is mainly used in paint, ink, plastic, paper, rubber and textiles. It has good color fastness and light resistance, and can be used for indoor and outdoor coatings, inks and plastic products. This pigment can also be used in the preparation of dye inks and high-strength plastic pigments.
synthetic chemical method is generally used for the preparation of Pigment normal Red F5RK. Specifically, 3-nitroaniline can be obtained by reacting aniline with nitrous acid, and then reacting with sodium M-methoxybenzene sulfate to form sodium 4-nitro-2, 5-dimethoxybenzene sulfonate. Finally, through the reaction with lead sulfate, Pigment last Red F5RK is obtained.
With regard to safety information, the pigmentation normal Red F5RK is relatively safe under normal conditions of use. However, it is still a chemical substance, and contact with eyes and skin should be avoided, and the inhalation of its dust should be avoided. During operation, it is necessary to wear appropriate protective equipment, such as gloves and protective glasses. In case of accidental contact or misuse, seek medical attention immediately. When storing and handling the pigment, follow the relevant safety procedures.
