Embodiment 1

[0039] A kind of synthetic method of ceramic ink solvent of the present embodiment is as follows:

[0040] (1) Preparation of sea urchin-like AlOOH: First, 1 mmol of aluminum sulfate and 4 mmol of urea were ultrasonically treated, then completely dissolved in a solvent composed of 100 mL of deionized water and 50 mL of absolute ethanol to obtain a mixed solution A, and then to the mixed solution A Add 2mL of oleic acid surfactant to the mixture and stir to obtain a mixed solution B, then put the mixed solution B into a 150mL reaction kettle, place the reaction kettle in an oven at 180°C for a high temperature reaction for 4h, obtain the product, and cool the product to At room temperature, after alternately washing and filtering with absolute ethanol and deionized water, put it into an oven at 60°C for 4 hours to obtain sea urchin-like AlOOH.

[0041] (2) Composite material SnO 2 / Fe 2 o 3 / Al 2 o 3 Preparation: 0.5 g of sea urchin-like AlOOH powder was dispersed in a mix...

Embodiment 2

[0045]The synthesis method of a kind of ceramic ink solvent of the present embodiment is basically the same as that of embodiment 1, and its difference is: the present embodiment adds the Fe(NO of 1:0.1 mass ratio in step (3). 3 ) 3 9H 2 O and SnCl 4 ·5H 2 O(where Fe(NO 3 ) 3 9H 2 The quality of O remains constant at 0.5g), the resulting solid acid catalyst SO 4 2- / SnO 2 / Fe 2 o 3 / Al 2 o 3 Labeled as 0.6-SSFeAl(1:0.1).

[0046] Then use solid acid catalyst 0.6-SSFeAl (1:0.1) to synthesize isooctyl palmitate.

Embodiment 3

[0048] The synthesis method of a kind of ceramic ink solvent of the present embodiment is basically the same as that of embodiment 1, and its difference is: the present embodiment adds the Fe(NO of 1:0.15 in mass ratio) in step (3). 3 ) 3 9H 2 O and SnCl 4 ·5H 2 O(where Fe(NO 3 ) 3 9H 2 The quality of O remains constant at 0.5g), the resulting solid acid catalyst SO 4 2- / SnO 2 / Fe 2 o 3 / Al 2 o 3 Labeled as 0.6-SSFeAl (1:0.15).

[0049] Then use solid acid catalyst 0.6-SSFeAl (1:0.15) to synthesize isooctyl palmitate.

Abstract

The invention provides a synthesis method of a ceramic ink solvent, which comprises the following steps: by using palmitic acid and isooctyl alcohol as raw materials, adding a solid acid catalyst to synthesize a ceramic ink solvent isooctyl palmitate. The solid acid catalyst is formed by taking aluminum oxide as a carrier, taking ferric oxide nanoparticles and stannic oxide nanoparticles as activeingredients and loading sulfate ions. The solid acid catalyst is controllable in morphology, large in specific surface area and good in stability, shows high catalytic activity on isooctyl palmitateserving as a ceramic ink solvent synthesized by esterification reaction, and can enable the isooctyl palmitate to have the characteristic of high conversion rate; and in the synthesis process of the isooctyl palmitate, the solid acid catalyst can be recycled, the synthesis cost can be reduced, the synthesis process is green and environment-friendly, and the synthesized isooctyl palmitate has the characteristics of stable performance, non-toxic volatile matter, low viscosity, moderate surface tension and the like, and is suitable for being used as a ceramic ink solvent.

Description

technical field [0001] The invention relates to the technical field of ceramic ink solvent synthesis, in particular to a method for synthesizing ceramic ink solvents. Background technique [0002] As the carrier of ceramic ink particles, ceramic ink solvent is an important component of ceramic ink. Its own components not only affect the stability of ceramic ink, but also ultimately affect the color of ceramic ink. Therefore, choose a low viscosity, moderate surface tension, and performance Stable, non-toxic volatile solvents are very important for ceramic inks, and the most used solvents for ceramic inks on the market are esters and hydrocarbons. Wherein, commonly used ester ceramic ink solvents have multi-carbon esters such as isooctyl laurate, isopropyl laurate, n-propyl laurate, and the present invention adopts self-made solid acid catalyst to synthesize ceramic ink solvent isooctyl palmitate ester. [0003] At present, industrially produced isooctyl palmitate is mostly...
