YieldReaction ConditionsOperation in experiment
EXAMPLE 1 C.I. Pigment Red 269 a1) Preparation of an Anisbase Diazonium Salt Solution: 242 g of <strong>[120-35-4]3-amino-4-methoxybenzanilide</strong> are initially stirred homogeneously into an initial charge of 2532 g of water at room temperature, precipitated by addition of hydrochloric acid and cooled down to 10 C. with 1.5 kg of ice/water. The precipitated hydrochloride is diazotized with 138 ml of sodium nitrite solution (40%) to finally give a readily stirrable anisbase diazo solution. This solution has a clarifying aid added to it and is subsequently filtered off into a feed vessel. Excess nitrite is removed by addition of amidosulfonic acid. A2) Preparation of a Buffer for the Anisbase Diazonium Salt Solution: To an initial charge of 1884 g of ice/water are added 502 g of acetic acid and also 614 g of aqueous sodium hydroxide solution, and the temperature is held at room temperature after addition of 1 kg of water. A3) Preparation of a Solution of the Coupling Component (Naphthol): An initial charge of 2720 g of water containing a wetting aid is heated to 80 C. While stirring, 328 g of N-(5-chloro-2-methoxyphenyl)-3-hydroxynaphthalene-2-carboxamide are introduced and dissolved alkalinically. By addition of a further 2720 g of ice/water, the Naphthol AS solution is cooled down to room temperature. It is finally filtered by addition of a clarifying aid. a4) Azo Coupling in Microreactor: The anisbase diazonium salt solution and the Naphthol AS solution are pumped at a flow rate of 8 ml/min into the respective reactant inlets of the microreactor (type: Cytos from CPC-Systems/Frankfurt). To achieve the requisite pH of 4.8-5.0 for azo coupling, the reactant solutions are diluted with the acetic acid/acetate buffer prepared according to a2), shortly upstream of the reactor inlets. The buffer solution is likewise conveyed with the aid of calibrated piston pumps via a T-junction into the reactant feed lines of the microreactor at a flow rate of 6 ml/min in each case. The heat exchanger circuit of the microreactor is connected to a thermostat which sets the desired reaction temperature of 20 C. to 35 C. The coupled pigment suspension (21 C., pH=5.0) is collected in a feed vessel and subjected to the following solvent wash. b) Solvent Wash: The pigment suspension obtained from the microreactor is admixed with such an amount of butoxyethanol that the entire slurry contains about 10% by volume of butoxyethanol. The slurry is stirred at about 45 C. for 30 minutes, filtered off and washed with water. After sampling, the colorant-solvent-water suspension is subjected to the following membrane purification. c) Membrane Purification: A ceramic multichannel microfiltration membrane having a nominal separation limit of 60 nm for the separation-selective layer and a membrane area of 0.09 m2 is used. About 15 kg of the colorant suspension having a pigment content of about 2% by weight are charged to a temperature-controllable feed vessel. The membrane is subjected to a pressure of about 1.5 bar on the retentate side at ambient temperature. To ensure a constant volume in the feed vessel, the mass of permeate removed is replaced with demineralized water in a discontinuous manner. The pigment is fully retained and the organic secondary components are reduced to the values listed in table 2, under these conditions. The exchange volume (i.e., volume of demineralized water supplied/volume of pigment suspension used) is about 4. Permeate flux is about 200 l/(m2·h·bar). At the same time, the initial chloride ion content of 2.5% is reduced by 10 hours of diafiltration to 920 ppm as is the sulfate content from initially 0.3% to 30 ppm. d) Analysis: The samples taken (each 0.5 g) are dried, admixed with 10 ml each of N-methylpyrrolidone and comminuted for 15 min by ultrasonication. After addition of 20 ml of methanol and renewed grinding for 15 min, the suspension is filtered off. In each case, 20 mul of the filtrate are introduced into the autosampler of the HPLC system and detected by UV-V is detector at 240 and 375 nm (separating column Nucleosil 120-5 C18 (length: 25 cm, ?i=4.6 mm); mobile phase consisting of a buffer (575 mg of NH4H2PO4 plus 1000 g of H2O plus 3.0 g of NaN3 (pH 5.0)) and methanol chromasolv in various compositions for a total flux of 1 ml/min).
