Abstract
The invention relates to an anti-blocking agent produced from soybean oil deodorizing distillate, as well as a production method and application of the anti-blocking agent. The fertilizer anti-blocking agent is characterized in that a byproduct generated in a deodorizing process of soybean oil refining is used as a raw material to react with diethanol amine to generate a surfactant fatty acid diethanolamide; the fatty acid diethanolamide and the soybean oil deodorizing distillate are mixed in a ratio of (0.5-1):1 to obtain the fertilizer anti-blocking agent with low condensation point. According to the fertilizer anti-blocking agent, the oil and fat refining byproduct is used as the raw material and is turned from waste to valuable things, so cost is low, while the prepared anti-blocking agent product is low in condensation point. Compared with a traditional anti-blocking agent product, the fertilizer anti-blocking agent is small in energy consumption when being used, and is convenient to operate and transport in the using process. The raw materials related in the anti-blocking agent can be biodegraded, thus the anti-blocking agent is an environment-friendly additive in the fertilizer industry.
Description
Technical field
The present invention relates to oil and fat chemical and utilize field, be specifically related to anti-hard caking agent and production method and application that a kind of soya-bean oil deodorizing overhead product is produced.
Background technology
Soybean oil, due to wide material sources, is rich in the unsaturated fatty acidss such as linolic acid, has become output maximum in the world, grease kind that range of application is the widest.Soya-bean oil, due to its distinctive beany flavor, therefore must increase deodorizing process, to improve mouthfeel and the local flavor of soya-bean oil in soya-bean oil refining process after depickling, decolouring.It is a kind of good lipid raw material that the by product soya-bean oil deodorizing overhead product that soya-bean oil produces in deodorizing process is rich in a large amount of lipoid materials.The anti-caking agent for fertilizer of preparing with soya-bean oil deodorizing overhead product can meet the coated requirement of chemical fertilizer granule, stops the generation of the brilliant bridge between chemical fertilizer granule, thereby reaches the object of anti-caking.In addition also solved the byproduct for treatment problem of oil refining plant.A kind of production method of anti-caking agent for fertilizer is disclosed in CN00134367.X.Be characterized in utilizing liquid caustic soda to process waste oils and fats and generate fatty acid sodium soap, then be mixed with anti-caking agent for fertilizer with grease.Anti-caking agent for fertilizer zero pour prepared by this method is high, when use, to be heated to 60-80 degree Celsius, north provinces and cities are used especially use meeting in winter to bring a large amount of energy costs to increase to fertilizer enterprises, and secondly fatty acid sodium soap can change the acid-base condition in soil, are unfavorable for a large amount of use throughout the year.A kind of processing method of environment-friendly type solvent-free fertilizer anti-caking agent is disclosed in CN02137925.4.Be characterized in utilizing waste oil pin, aste vegetable oil and animal fat to prepare lipid acid for raw material, add tensio-active agent and prepare anti-caking agent for fertilizer.This invention may be given in soil and be brought the Phenylsulfonic acid class tensio-active agent relating in embodiment into, brings difficulty to natural degradation; The lipid acid of high acid value calcium magnesium soapization in alkaline soils has also limited its use in alkaline soils.Oil source difference is also had higher requirement to the suitability of independent use nonionogenic tenside.
The present invention is directed to the shortcoming and defect of existing patent, design and utilized soya-bean oil deodorizing overhead product to react preparation HLB value mixed fatty acid diethanolamine tensio-active agent widely with diethanolamine, reduce the cost of raw material, also increased the emulsifying effectiveness of fats raw material, be more conducive to the release of fertilizer in soil, the acid-base condition that can not change fertilising soil simultaneously, suitability is stronger.
Summary of the invention
The object of this invention is to provide one taking soya-bean oil deodorizing overhead product as raw material, produce the processing method of anti-caking agent for fertilizer.
A kind of soya-bean oil deodorizing overhead product is produced the production method of anti-hard caking agent, it is characterized in that: the by product producing in the deodorizing process with soya-bean oil refining is that raw material reacts with diethanolamine, making soya-bean oil deodorizing overhead product in by product raw material and the mass ratio of diethanolamine is 5:1-6:1, the fatty acid diethanolamine that reaction makes mixes taking mass ratio as 0.5:1-1:1 with soya-bean oil deodorizing overhead product again, obtains the anti-caking agent for fertilizer of low condensation point.
As further improvement, using the by product soya-bean oil deodorizing overhead product producing in the deodorizing process of soya-bean oil refining is main raw material.
As further improvement, soya-bean oil deodorizing overhead product participates in reacting according to mass ratio 5:1-6:1 with diethanolamine.Control temperature at 150-160 DEG C, mixing speed 30-60r/m, reaction time 2-4h, controlling the acid number of reaction system, to be less than 2 be that termination reaction obtains reaction product fatty acid diethanolamine.
As further improvement, the fatty acid diethanolamine that reaction obtains is 0.5:1-1:1 with the mass ratio of the soya-bean oil deodorizing overhead product that does not participate in reacting, and mixing temperature is 40-50 DEG C, and mix and blend rotating speed is 60r/m.
The anti-caking agent for fertilizer that the above-mentioned method of use is produced, be brown color suspension liquid at 25 DEG C of described anti-caking agent for fertilizer, is applicable to nitro-compound fertilizer, urea-base compound fertilizer, BB fertilizer and various monomer fertilizer.
An application for anti-caking agent for fertilizer described above, it is characterized in that in the time of compound fertilizer granulating, adding chemical fertilizer in or adopt composite fertilizer surface spraying.
As further improvement, the interpolation quality of described anti-hard caking agent in chemical fertilizer is the 0.2%-0.4% of chemical fertilizer total mass.
Beneficial effect of the present invention is: the anti-caking agent for fertilizer zero pour of utilizing soya-bean oil deodorizing overhead product to prepare for raw material is low, uses enterprise energy loss low, and the restriction in region and season is little, is especially applicable to medium and small fertilizer enterprises.The tensio-active agent HLB value scope that reaction generates is wide, the emulsifying effectiveness of lipoid material is better than the tensio-active agent adding separately, and do not add the lipid acid soap-like matter that may change soil acidity or alkalinity, table is lived composition also can be degradable in soil, do not bring environmental problem.
