Embodiment 1

[0026] Add 53.0g of manganese dioxide and 178.0g of isooctanoic acid into a 500mL four-neck flask equipped with mechanical stirring, thermometer, constant pressure dropping funnel, and nitrogen inlet, and replace nitrogen twice. At room temperature, add 240g of hydrogen peroxide and hydrogen peroxide The dropping time is controlled at 0.5h, and the temperature is controlled at 60-70°C. After the dropwise addition, the reaction is 2h, and then the temperature is raised to 90°C, and the reaction is 5h. The density is -0.1MPa. Remove the water generated by the reaction in the system to obtain a reddish-brown viscous liquid, which is the product. Finally, add C9 aromatic hydrocarbon solvent oil to prepare a drier with a manganese ion content of 7.5%.

Embodiment 2

[0028] Add 53.0g of manganese dioxide and 178.0g of isooctanoic acid into a 500mL four-neck flask equipped with mechanical stirring, thermometer, constant pressure dropping funnel, and nitrogen inlet, and replace nitrogen twice. At room temperature, add 240g of hydrogen peroxide and hydrogen peroxide The dropping time is controlled at 0.5h, and the temperature is controlled at 60-70°C. After the dropwise addition, the reaction is 2h, and then the temperature is raised to 90°C, and the reaction is 5h. The density is -0.09MPa, remove the water generated by the reaction in the system to obtain a reddish-brown viscous liquid, which is the product, and finally add C10 aromatic solvent oil to prepare a drier with a manganese ion content of 9.6%.

Embodiment 3

[0030] Add 53.0g of manganese dioxide and 178.0g of isooctanoic acid into a 500mL four-neck flask equipped with mechanical stirring, thermometer, constant pressure dropping funnel, and nitrogen inlet, and replace nitrogen twice. At room temperature, add 240g of hydrogen peroxide and hydrogen peroxide The dropping time is controlled at 0.5h, and the temperature is controlled at 60-70°C. After the dropwise addition, the reaction is 2h, and then the temperature is raised to 90°C, and the reaction is 4h. The density is -0.08MPa. Remove the water generated by the reaction in the system to obtain a reddish-brown viscous liquid, which is the product. Finally, add C9 aromatic hydrocarbon solvent oil to prepare a drier with a manganese ion content of 8.3%.

Abstract

The invention discloses a synthetic method of manganese iso-octoate and a preparation method of an ink drier, and the synthetic method comprises the following steps: step 1, putting a certain amount of manganese dioxide and isocaprylic acid into a reactor, and carrying out nitrogen replacement; step 2, dropwise adding hydrogen peroxide as a catalyst into the reactor at a constant speed, controlling the temperature at 60-70 DEG C, and reacting for 1-3 hours; 3, continuously heating to 85-95 DEG C, and reacting for 4-6 hours; and 4, carrying out reduced pressure distillation, and extracting water from the system. According to the preparation method of the ink drier disclosed by the invention, manganese iso-octoate is added into C9 or C10 aromatic solvent oil to prepare the drier with the manganese ion content of 7-10%, the synthesized ink drier takes hydrogen peroxide as a catalyst, the generated wastewater is less, the printing ink drier is green and environment-friendly, the cost is saved, the production process is simple, and the process is easy to control.

Description

technical field [0001] The invention relates to the technical field of printing ink auxiliaries, in particular to a method for synthesizing manganese isooctanoate and a method for preparing an ink drier. Background technique [0002] The traditional method of cooperating with cobalt salt and manganese salt as the main drier, and auxiliary drier such as lead, zinc, calcium, iron, and rare earth has a history of nearly a hundred years. In recent years, a new type of drier - isooctanoate has been developed. Compared with the traditional naphthenate drier, it has good solubility, less dosage, high purity, light color, light odor and low viscosity. And other advantages, it is widely used as additives for various ink coating driers, fuels and lubricating oils, and has gradually or will completely replace naphthenic acid products. [0003] Manganese drier is the main component of mixed drier, which has good bottom drier performance, and it can improve the toughness and hardness of...
