Abstract
The invention discloses a method for producing alkenyl succinic anhydride. The method is as below: preheating reaction materials in a reaction kettle, completely melting; first heating to 125 to 180 DEG C, reacting at a constant temperature for a period of time, then continuing heating to 190 to 230 DEG C, and optionally insulating for a period of time until the end of the reaction. The method has reasonable process; the added middle constant temperature reaction section increases the fully mixing of the reactants and the degree of effective reaction, so as to effectively reduce the occurrence of side reaction, and greatly improve the purity and color of the product.
Description
Technical field
The present invention relates to the process of a kind of new and effective production ASA (alkenyl succinic anhydride).
Background technology
Paper industry is the chemical process industry (CPI) with fiber as raw material, in slurrying, bleaches, pulls an oar, manufactures paper with pulp
And each stage of one-tenth this technique overall process of paper conversion, all it be unable to do without the application of various chemicals.They
Have can give the various special superior function of paper (as water-resistance, grease resistance, wet strength, flatness,
Printability, flexibility etc.), the fibrous raw material making employing poor produce thinner, more in vain, more firm
Paper be possibly realized;Can make production process optimization, the paper machine operation speed that have improve, and the most significantly subtract
Few environmental pollution, brings good economic benefit to paper industry.
China's paper chemicals industry is started late, and to 20th century the mid-80, just starts progressively
Development.1986 Technology Bureaus of Nian Yuan the Ministry of Chemical Industry, papermaking office of former China National Light Industrial Products Department have held the whole nation in Hangzhou united organization
Papermaking chemical product technology forum, can on propose and accelerate exploitation and the application of China's papermaking chemical product, add
The strengthening work demand for development worked hard in glove with and cooperate interdepartmental with papermaking two.By 1994, China's paper chemistry
The exploitation of product there has been with production and develops faster, as various novel sizing agents, dry (wet) reinforcing agent,
Retention (filter) agent, dispersant, flocculant, defoamer, lubricant, coating adhesive, waterproofing agent,
Fire retardant, softening agent, waste paper deinking agent etc., through studying, develop, producing, obtain in paper plant
It is widely applied.
In pulping and paper-making production process add chemicals, a class belongs to basic chemical raw materials, as Caustic soda,
Alumina etc.;Another kind of, it is addition less pulping and paper making chemistry auxiliary agent.The latter is pulping and papermaking processes
In in order to improve some characteristic of paper pulp or paper, reduce supplies consumption and improve operating condition etc., to master
The general name of a small amount of chemical substance added in material.The most also pulping and paper making chemistry auxiliary agent is referred to as papermaking
Product.Papermaking chemical product presses paper-making process classification, can be divided into pulping chemical, copy paper chemicals and add
Work paper chemicals three major types.Wherein copy paper chemicals includes: internal sizing agent, Cypres, humidification
Strong agent, drying strengthening agent, fluidizer filter aid, paper softener, dispersing agent for fibre, paper dyestuff, fluorescence increase
White agent, felt abluent etc..Wherein internal sizing agent refers to that sizing agent makes an addition in paper pulp, executes to play
Glue effect, typically have Colophonium saponification glue, Pexol, dispersion rosin size (Dispersed Anionic Rosin Size,
Cationic dispersion rosin size), alkyl ketene dimer (AKD) and alkenyl succinic anhydride (ASA) isoreactivity
Sizing agent, petroleum resin sizing agent etc..
ASA is in modern paper industry, produces the neutral sizing agent used by fine paper.In current papermaking
Industry, neutral sizing has become as the main flow of technology development.In neutral sizing agent, topmost product is exactly
AKD and ASA.Both sizing agents, due to its respective feature, all obtain in paper industry at home and abroad
It is widely applied.ASA is fast due to its lower machine ripening, the spies such as absolute dosage is little, and on-the-spot emulsifying technology is ripe
Point, is the most progressively more widely used.Particularly in painting processing paper field, owing to body paper produces
To be coated processing afterwards at once, so, the feature of ASA has obtained sufficiently sending out in painting processing paper
Wave, and obtained the generally accreditation of industry.But, due to ASA on-the-spot emulsifying device substantially by
External papermaking chemical product company provides, and cost is higher.And, ASA raw materials for production at home mainly by
Import meets, and does not use suitable catalyst, and productivity is relatively low, and cost is high.So for some
The papermaking enterprise that scale is less, the interest of ASA supplier is little.Entirety along with China's papermaking enterprise scale
Improving, or the production domesticization of ASA emulsifying device is to reduce the threshold using ASA, ASA sizing agent is bound to
China's paper industry is occupied more importantly position.
In prior art, with C13-C14Interior alkene and maleic anhydride be raw material, prepare alkenyl succinic anhydride
(ASA), under current process conditions product yield less than 55%.Further, and due to operating condition not
Enough perfect, often cause side reaction to increase, product purity reduces, and outward appearance and color and luster are poor.
