摘要:The present invention relates to the technical field of fine organic chemicals, and provides a continuous synthesis method for a disperse yellow dye. Continuous tubular reaction technology is used. A continuous tubular reactor provided by the present invention has a small volume, a large specific surface area, and a large heat transfer area per unit volume. The continuous tubular reactor can promptly transfer reaction heat by means of heat exchange and can ensure safety while accelerating the feeding speed. The continuous tubular reaction provided by the present invention precisely controls a raw material ratio, so that a feeding ratio of main raw materials is close to a theoretical value. In addition, by means of introducing an automatic control system, the chemical reaction can be carried out at a raw material ratio that strictly follows an optimal set value. The mass transfer and heat transfer effect of the continuous reactor is relatively good. Following the improvement to the mass transfer and heat transfer effect, the temperature control is more precise, and the generation of by-products is reduced.

标题 :Solid dyestuff formulations containing ethylenically unsaturated acid, ester and acrylonitrile copolymer

摘要:Solid dyestuff formulations having excellent dyebath stability are obtained in an economical manner by mixing a water-insoluble textile dyestuff with a dispersant and a carboxyl-containing copolymer of n (a) an α,β-ethylenically unsaturated monocarboxylic acid, n (b) a non-basic ester of an α,β-ethylenically unsaturated monocarboxylic acid, and n (c) an unsaturated aliphatic or aromatic hydrocarbon or acrylonitrile, n bead-milling the mixture down to a particle size of, preferably, 1-2μ, and then spray-drying the ground mixture. If desired the dispersant can also be added during the synthesis of the dyestuff, as a consequence of which early addition the milling process can be dispensed with.
