Problems solved by technology

But these two types of reactions have a common shortcoming, that is, in order to obtain high-purity metal oleate, it is necessary to use expensive purified oleic acid, thus increasing production costs, and the product purity is still not high

Embodiment 1

[0028] Take 20mmol of ferric chloride hexahydrate and 60mmol of sodium oleate in a 500ml one-necked flask, add 20ml of deionized water, 200ml of absolute ethanol and 60ml of n-hexane, and add a suitable magnet. Connect the single-necked flask to a spherical condenser, place it on a magnetic stirrer with a heating mantle, and use a thermocouple to control the temperature. Using condensed water to reflux, the reaction temperature was maintained at 120° C., and the reaction time continued for 5 hours. After the reaction was completed, the solution was poured into a separatory funnel and left to stand for a period of time. After the solution was completely separated, the lower transparent water phase liquid was let off to obtain a yellow oily liquid. Wash the yellow oily liquid with deionized water, let it stand again, let off the lower layer of aqueous phase liquid, and wash three times. Pour the washed yellow oily liquid into a 250ml beaker, add a magnet, heat on a magnetic sti...

Embodiment 2

[0031] Take 40mmol of CoCl 2 and 40mmol magnesium oleate were placed in a 500ml single-necked flask, and 60ml of deionized water, 120ml of absolute ethanol and 120ml of toluene were added, and a suitable magnet was added. Connect the single-necked flask to a spherical condenser, place it on a magnetic stirrer with a heating mantle, and use a thermocouple to control the temperature. Using reflux of condensed water, the reaction temperature was maintained at 200° C., and the reaction time was continued for 0.5 hours. After the reaction is completed, the solution is poured into a separatory funnel and left to stand for a period of time. After the solution is completely layered, the lower layer of transparent water phase liquid is released to obtain an oily liquid. Wash the oily liquid with deionized water, let it stand, let off the lower layer of water phase liquid, and wash three times. Pour the washed oily liquid into a 500ml beaker, add a magnet, place it on a magnetic stirr...

Embodiment 3

[0034] Take 10mmol of MnCl 2 and 20mmol potassium oleate were placed in a 250ml single-necked flask, and 20ml of deionized water, 80ml of absolute ethanol and 30ml of benzene were added respectively, and a suitable magnet was added. Connect the single-necked flask to a spherical condenser, place it on a magnetic stirrer with a heating mantle, and use a thermocouple to control the temperature. Using reflux of condensed water, the reaction temperature was maintained at 80° C., and the reaction time was continued for 10 hours. After the reaction is completed, the solution is poured into a separatory funnel and left to stand for a period of time. After the solution is completely layered, the lower layer of transparent water phase liquid is released to obtain an oily liquid. Wash the oily liquid with deionized water, let it stand, let off the lower layer of water phase liquid, and wash three times. Pour the washed oily liquid into a 250ml beaker, add a magnet, place it on a magneti...

Abstract

The invention relates to a preparation method for metal oleate, belonging to the preparation method of metal organic compounds. The preparation method for the metal oleate comprises the following steps of: using an ion exchange method to prepare the metal oleate; adopting alkali or alkaline-earth metal oleate and metal inorganic compounds as reactants, and mixing the reactants in the solvent containing water phase and oil phase; heating, stirring and reacting for certain time to form a layered mixed solution; and carrying out evaporating separation treatment on the oil phase to obtain high-purity metal oleate. The preparation method provided by the invention can prepare high-purity metal oleate by optimizing the reaction processes and synthesis conditions, is used for preparing a high-performance mono-disperse inorganic nanometer material, and is a green process for metal ion recycling. Besides, the preparation method has the characteristics of low preparation cost, economical efficiency, environmental-friendliness, and easiness in industrialization.

Description

Technical field: [0001] The invention relates to a preparation method of metal oleate, which belongs to the preparation technology of metal organic compounds and also belongs to the green manufacturing technology of metal ion recovery. Background technique: [0002] Metal oleate refers to the combination of metal cations and a certain number of oleic acid anions to form metal organic compounds, and its chemical formula is generally M n+ (C 17 h 35 COO - )n, the English name is Metal Oleate. Humans have long applied metal oleates to people's lives, such as sodium oleate, which is widely used in soaps, has strong detergency, good biodegradability, no toxic side effects on the human body, and no pollution to the environment. [0003] Since the development and utilization of metal oleate, the research on the synthesis, properties and application of metal oleate has continuously made important progress. Metal oleate has a wide range of applications in science and technology,...
