Problems solved by technology

This kind of demulsifier composed of a mixture of various components, because it contains more free oleic acid, the actual use makes the oil and water two phases separate for a long time, and the phase is not clear.
Secondly, the base material of the demulsifier - polyethylene polyamine, the demulsification ability is not strong enough, so that the actual use of the demulsifier is relatively large
In addition, this demulsifier has a relatively unpleasant smell, which brings inconvenience to actual use.

Embodiment 1

[0017] Example 1: 300 kilograms of erucic acid (docosanoic acid), 145 kilograms of triethylenetetramine, and 200 kilograms of xylene were put into a reaction kettle, heated and stirred to react at 120-170° C., acylated and dehydrated, dehydrated Stay hydrated. Vacuum distillation removes xylene to obtain the product erucoyl triethylenetetramine C 21 h 41 CONH(CH 2 CH 2 NH) 3 H.

Embodiment 2

[0018] Example 2: 283 kg of oleic acid (octadecenoic acid), 232 kg of pentaethylene hexamine, and 150 kg of xylene were put into the reaction kettle, and heated and stirred to react at 120-160° C. for acylation and dehydration. moisture. Vacuum distillation removes all xylene to obtain the product oleoyl pentaethylene hexamine.

Embodiment 3

[0019] Embodiment 3: put 263 kilograms of oleic acid (octadecenoic acid) into the reaction kettle, 230 kilograms of polyethylene polyamines, 220 kilograms of xylenes, heat and stir to react to 120-170 ℃, carry out acylation dehydration, remove completely moisture. Vacuum distillation removes all the xylenes to obtain the product oleoylpolyethylenepolyamine.

Abstract

The demulsifier for demulsification of penicillin fermenting liquor is characterized by that it is made from 50-80% of acidamide, 20-50% of alkylamine polyethenoxy ether and 0-20% of additive by mixing. It overcomes the defect of demulsifier formed by simple-kmixing deic acid, polyethylene amine and alkyl diethanolamine, and possesses strong desmulsification power, not only possesses high demulsification efficiency, but also can economize production cost, and can raise yield, can make yield stable in above 94%, and has good impurity-removing rate.

Description

technical field [0001] The invention relates to a demulsifier for oil-water separation of fermented liquid, especially for the demulsified separation of penicillin fermented liquid. Background technique [0002] The most simple and effective method for the effective separation of the organic phase and the aqueous phase is to use a demulsifier to eliminate emulsification and form an emulsified interface with a certain strength to achieve two-phase separation. However, different demulsifiers have different abilities to demulsify the organic phase, and the performance of the demulsifier directly affects the separation effect of the two phases. In the production process of penicillin, an important process is to extract penicillin from penicillin fermentation broth with organic solvent (such as butyl acetate). The interface of the water phase is not clear, and it is an emulsified area with a certain intensity, which has a great influence on the yield of the finished product. Th...
