Abstract
The invention discloses amido omodified phenolic resin and a preparation method thereof. The preparation method of the amido omodified phenolic resin comprises the following steps: firstly, enabling phenol compounds and one part of aldehyde compounds to generate phenolic aldehyde compounds under the action of an acid catalyst; then, adding sequentially vinyl amine compounds and the rest of aldehyde compounds to react, thereby finally obtaining the amido omodified phenolic resin, wherein the molar ratio of the phenol compounds to the aldehyde compounds to the vinyl amine compounds is 1.00 to (1.00-2.80) to (0.15-2.50). The preparation method has the advantage that an intramolecular mixing technology is adopted to integrate a plurality of benzene rings with a plurality of reactive hydrogen structures into an initiator molecule, namely molecules of the amido omodified phenolic resin; an aromatic structure and a plurality of reactive hydrogen atoms are provided in the molecular structure of the amido omodified phenolic resin at the same time, so that the amido omodified phenolic resin can be used as an initiator for an aromatic multi-branched emulsion breaker for oil field raw oil dehydration and refinery plant raw oil dehydration and desalination.
Description
Technical field
The present invention relates to a kind of amino modified resol for the preparation of emulsion splitter initiator and preparation method thereof, belong to Petroleum Processing Technology field.
Background technology
In crude production, crude oil normally water-in-oil or O/w emulsion form exist, water and be dissolved in the process such as production, transport, refining of electrolytical existence wherein to crude oil and have extremely adverse influence, therefore must be down to former Water in oil within acceptable scope by breakdown of emulsion or dehydration.At present, breakdown of emulsion or dewatering comprise gravity (or centrifugal force) settling process, heat treating process, electric field treatment method and chemical demulsification method, and the chemical demulsification rule reaching crude oil demulsification or dehydration by adding chemical demulsifier in emulsion of crude oil is the most frequently used and most effective means.People to the research of chemical demulsification method very early, develop a large amount of emulsion splitters.Current, most widely used emulsion splitter is mainly based on the polyethers of Pluronic F-127 polycyclic oxypropylene copolymer.This type of emulsion splitter is using the compound containing reactive hydrogen as " initiator ", at effect and the segmented copolymer carrying out ring-opening polymerization with oxyethane, propylene oxide and obtain respectively of ring opening catalyst.Generally speaking, the emulsion splitter performance having different initial polyethers is different.Wherein comparatively speaking, the polyether demulsification agent taking resol as initiator is very fast to the rate of water loss of the light crude emulsion containing less pitch, and the polyether demulsification agent being initiator with amino modified phenolic compound is then very fast to the emulsion of crude oil rate of water loss containing more pitch.The application that this two classes emulsion splitter all industrially obtains.But this two classes emulsion splitter all exists the narrow shortcoming of adaptability, this brings certain restriction to applying of this two types product, particularly in the oil field that some individual well production fluids differ greatly.Take phenol-amine resin as the product advantage that the polyether type demulsifying agent of initiator has then gathered this two type, namely racemosus structure is had in their molecular structure, there is aromatic structure again, therefore such emulsion splitter not only has that rate of water loss is fast, the feature of less developer, also have the wide scope of application, crude oil production fluid that is more to bituminous and that contain paraffin more all has good treatment effect.What Chinese patent CN201310683689, CN201310347875, CN201210581160, CN201210115016, CN201110108168, CN200710010069, CN200610057168, CN200610057168, CN200310105425 and CN200310105425 reported is all this take phenol-amine resin as the polyether demulsification agent of initiator.But report in these patents with phenol-amine resin to be that the shortcoming of the polyether demulsification agent of initiator is in their molecular structure general only containing an aromatic group, that is, the aromaticity of this emulsion splitter molecule is very low.And according to modern breakdown of emulsion Theory and applications experience, when the oleophilic group of emulsion splitter and emulsifying agent have similar structure and molecular weight is close, the effect of breakdown of emulsion is often better.The emulsifying agent that in crude oil, content is at most, emulsifying capacity is the strongest is bituminous matter, and bituminous matter is a kind of polynuclear compound of aromaticity, its molecular weight about hundreds of between thousands of.Therefore with regard to similarity, conventional phenol-amine resin obviously and asphaltene molecules structurally there is notable difference, this also just limits applying more widely with the conventional phenol-amine resin polyether demulsification agent that is initiator.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of novel amino modified resol and preparation method thereof, there is in the molecular structure of this amino modified resol two or more aromatic structure and multiple reactive hydrogen atom simultaneously, structurally more similar with bituminous matter, can be used as the initiator of the hyper-branched emulsion splitter of aromaticity of crude oil dehydration and refinery's dehydrate and desalt of crude oil.
