High-dispersity and high-stability octadecyl amine emulsion processing equipment and process

Abstract

The invention discloses high-dispersity and high-stability octadecyl amine emulsion processing equipment. The equipment is an open-mouth container, wherein a drain valve and a self-sucking pump are mounted on a discharge pipeline at the bottom of the open-mouth container. The processing technique of the processing equipment is as follows: (1), injecting demineralized water into the container; (2), adding octadecyl amine solid into the demineralized water; and (3), adopting a high-shearing and mixing emulsifying machine for preparing octadecyl amine emulsion. According to the invention, the single high-shearing and mixing emulsifying machine equipment is used for producing the high-dispersity and high-stability octadecyl amine emulsion in one step; and the manufacturing process and the operation are simple and convenient so that the costs for the equipment and the procedures are reduced. The clearance between a rotor and a stator of the high-shearing stirring head of the emulsifying machine can be adjusted and selected, the mechanical shearing force is enabled to be improved greatly, the particle sizes of the sheared octadecyl amine particles are enabled to be smaller, and the dispersity of the octadecyl amine emulsion is enabled to be greater. Therefore, the emulsion is enabled to be more stable. The preserve time of emulsion processed in the invention is more than 180 days, and is prolonged by more than 3 times compared with the preserve time of emulsion produced in the prior art.

Description

technical field [0001] The invention relates to pure octadecylamine emulsion processing equipment and technology, in particular to a processing equipment and technology with high dispersion and high stability octadecylamine emulsion. Background technique [0002] Octadecylamine, also known as octadecylamine, belongs to aliphatic amines, is alkaline, easily soluble in chloroform, soluble in ethanol, ether and benzene, slightly soluble in acetone, hardly soluble in water, and has a density of 860kg / m 3 , the freezing point is 52.9°C, and the boiling point is 348.8°C. Octadecylamine can be hydrolyzed in water, and combined with some hydrogen ions in water, the concentration of hydroxide ions in the solution increases relatively, and the solution is weakly alkaline. [0003] Industrial use of octadecylamine: used to make octadecyl quaternary ammonium salt and various additives, such as cationic grease thickener, mineral flotation agent, asphalt emulsifier, antistatic agent, cor...

Problems solved by technology

[0014] Because power plant users cannot obtain accurate information on the composition and content of additives, and cannot judge the impact of additives on the unit, the addition of additives makes the safety of using this octadecylamine emulsion questionable.

[0015] In summary, pure stearylamine emulsion needs to be improved and improved in terms of stability and dispersion particle size, and the existing technology cannot well meet the practical application
