A perylene pigment preparation method

The present invention provides a perylene pigment preparation method, is to adopt the N - substituted - 1, 8 - naphthalene imide as the starting material, in order to N - methyl imidazole with DBU or DBN N - methyl imidazole with the mixed solvent as reaction medium, sodium alcoholate or polysiloxane as catalyst, through 130 - 170 °C reaction 3 - 10 hours, after the reaction, the reaction system cooling, concentrated under reduced pressure, recycling the reaction solvent, collects the product make the perylene pigment. Preparation of perylene pigment coloring high, bright color, good dispersibility, and this process is simple, time consuming and short, the reaction temperature is low, to reduce the use of strong alkali and concentrated sulfuric acid, the production cost is reduced, the reduction of the waste water and the solid waste discharge.

[...] derivatives and their use

The invention relates to an N,N'-dimethyl-3,4,9,10-perylenetetracarboxylic diimide derivative and application thereof. The N,N'-dimethyl-3,4,9,10-perylenetetracarboxylic diimide derivative refers to the compound shown as a formula II in the specification or salts thereof. The designed and synthesized N,N'-dimethyl-3,4,9,10-perylenetetracarboxylic diimide derivative can be used for preparing perylene pigments such as C.I.pigment red 149. The perylene pigment prepared by the N,N'-dimethyl-3,4,9,10-perylenetetracarboxylic diimide derivative disclosed by the invention has large specific surface area and narrow particle size distribution.

Soluble Perylene Fluorescent Dyes with High Photostability

The preparation of several 3,4,9,10-perylenebis(dicarboximides) 1 is described and their photostability quantitatively determined and discussed.It is shown, that substitution of the insoluble perylene dye pigments with tert-butyl groups causes solubility in organic solvents leading to high quantum yields of these dyes.
