Abstract
The present invention relates to a demulsifier for the oil-water separation of fermented liquor, particularly to the use for the demulsification of penicillin fermentation liquor, which is characterized in that the demulsifier is made from 50 to 80% of acid amide, 20 to 50% of alkylamine polyoxyethylene ether and 0 to 20 % of additive agent. The present invention overcomes the defects of a demulsifier which is made from oleic acid, multiple vinylamine and alkyl diethanolamine, and all the materials are simply mixed. The present invention has the advantages of strong demulsifying performance, good demulsifying effect and small dosage. In particular, the present invention which is used for the demulsification of the penicillin fermentation liquor has high demulsifying efficiency, saves productive cost, and increases yield coefficient, and yield coefficient can be stabilized above 94%. Impurity removing efficiency is good, and impurities and chromatophore bands are difficult to enter the demulsifier which does not have unpleasant odor.
Description
Technical field
The present invention relates to a kind of demulsifier for oil-water separation of fermented liquid, the breakdown of emulsion that is particularly useful for penicillin fermentation liquid separates.
Background technology
Organic facies is effectively separated with water, and a kind of simple effective method is to adopt demulsifier, eliminates emulsification and forms the emulsification interface with certain intensity, reaches two and is separated.Yet different demulsifiers is different to organic facies breakdown of emulsion ability, and the performance of demulsifier directly influences the two-phase separating effect.In the penicillin production process, an important procedure is to use extracting penicillin with organic solvent (as butyl acetate) from penicillin fermentation liquid, owing to contain the complicated thing of protein, carbohydrate, mycelium etc. in the zymotic fluid, the interface of organic facies and water is unclear during extraction, the emulsion band that is certain intensity is very big to the influence of finished product yield.Must use the demulsifier breakdown of emulsion for this reason, eliminate emulsion, reach two-phase and effectively separate fast.
The performance of demulsifier directly influences the yield of penicillin, Chinese patent 95111376 disclosed a kind of penicillin demulsifier for oil-water separation, and it is made up of through mixing the oleic acid of 30-41%, the ethyleneamine of 30-41%, the alkyl diethanol amine of 18-40%.This demulsifier of forming by the multiple components mixture owing to contain more free oleic acid, actual use make oil, water two phase stratification time long, mutually in unclear wash rice.Secondly, this demulsifier base-material---polyethylene polyamine, the breakdown of emulsion ability is strong inadequately, makes that the actual demulsifier consumption that uses is relatively large.In addition, this demulsifier exists than niff, makes troubles for actual the use.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of breakdown of emulsion ability strong, good combination property, consumption is few, and the demulsifier for oil-water separation of fermented liquid of free from extraneous odour.
The object of the invention realizes, the main improvement is to adopt acid amides to make the demulsifier base-material, all mixes with the alkylamine APEO is composite, for further improving the breakdown of emulsion ability, the additive that also can add 0-20% in the demulsifier of the present invention is as antistatic additive and/or wetting agent and/or bleeding agent and/or sedimentation agent.Specifically, demulsifier for oil-water separation of fermented liquid of the present invention is characterized in that having the acid amides of 50-80%, and the alkylamine APEO of 20-50%, the additive of 0-20% mix to be formed.
The said acid amides of the present invention is to be mixed by mole ratio with ethyleneamines by alkyl acid (olefin acid or alkane acid), through acidylate dehydration products therefrom.Be about to the acid of olefin acid or alkane and mix by mole ratio, add the dimethylbenzene dehydrating agent and be heated to 120-180 ℃, remove water generation reaction and dimethylbenzene with ethyleneamines.Reaction expression is
, R wherein
1Be C
10-C
22Alkyl, n is 2-n.Acid amides of the present invention better adopts the dehydration of olefin acid and ethyleneamines acidylate, especially adopts the dehydration of oleic acid and multiethylene polyamine acidylate to obtain the oleoyl multiethylene polyamine, more is applicable to the breakdown of emulsion of penicillin fermentation liquid.
The said alkylamine APEO of the present invention is by alkylamine (RNH
2) and oxirane (CH
2CH
2O) a kind of polyether compound that generates through the base catalysis reaction, reaction expression is:
, wherein R is C
10-C
20Alkyl, n is 4-12.
Antistatic additive of the present invention, wetting agent, bleeding agent, sedimentation agent can adopt the commercially available prod, have no special requirements.Look actual conditions, single use and/or mixed use all can.
The preparation of demulsifier of the present invention: will be by acid of olefin acid or alkane and ethyleneamines acidylate dehydration gained acid amides 50-80%, with mix with oxirane base catalyzed reactions gained alkylamine polyoxy ether 20-50% by alkylamine heat composite.As add additive, also can add additive after, once heating all, it is composite to mix.The present invention's purpose of heating is to make the compound can be more even.
Demulsifier of the present invention, owing to adopt acid amides to make the demulsifier base-material, composite again alkylamine APEO with permeability and antistatic behaviour, both synergies have overcome by oleic acid, ethyleneamine, the simple deficiency of mixing of alkyl diethanol amine.Demulsifier of the present invention can be got rid of the interference of electric double layer, rapidly near the emulsification interface, makes two-phase interface more easily separated, thereby zymotic fluid breakdown of emulsion ability is improved greatly, and demulsification is good, and consumption is few, only needs about 100ppm.The present invention adopts oleic acid and the dehydration of multiethylene polyamine acidylate to obtain the oleoyl multiethylene polyamine, the demulsifier of the composite composition of octadecylamine polyoxyethylene (9) ether that obtains with octadecylamine and reacting ethylene oxide, the breakdown of emulsion that is particularly useful for penicillin fermentation liquid, breakdown of emulsion separating effect height not only, and can also improve the penicillin yield, yield can be stabilized in more than 94%, and impurities removing efficiency might as well, impurity and pigment are brought into few, there is not the residue of this demulsifier in mutually at the ester of extract layer, help improving the penicillin end product quality, save the penicillin production cost; And do not have bad smell, welcome by the pharmaceutical factory workman.Demulsifier of the present invention to the penicillin fermentation liquid demulsification see Table 1, table 2.
