Description
Technical field
The present invention relates to the field that metallic impurity elements is deviate from the plant chemical industry, be specially the method for deviating from that relates to impurity aluminum in the rosin.
Background technology
Rosin is to be raw material with rosin, through operations such as fusion, filtration, clarification and vapor distillation processing forming by resinous acid, lipid acid and neutral substance of obtaining.In the contained micro-metals of rosin, aluminium is a kind of harmful element, as causing brain injury, memory loss, cause senile dementia, directly damaging osteoblastic activity, thereby the matrix that suppresses bone is synthetic etc., is a kind of comparatively sensitivity, influence the very strict impurity of a kind of requirement that rosin is used in foodstuff additive.When rosin further is processed into foodstuff additive, when being used for chewing gum, bubble gum, beverage emulsifying stabilizer and used for packing foods tackiness agent, impurity aluminum content in the rosin has been proposed high requirement, the hot melt blend of general complexity, because rosin raw material sources difference, impurities exists than big difference, requires in the rosin aluminium content massfraction below 10ppm.Though domestic rosin is because of the raw material sources difference, its aluminium content is in wide fluctuations very, and generally higher, aluminium content massfraction generally more than 50ppm, for satisfying rosiny service requirements in the industry such as food, must carry out dealumination treatment to it in the rosin.
Summary of the invention
The object of the present invention is to provide a kind of technical process simple, the treatment time is short, processing ease, safety, the method for deviating from aluminium in the rosin that the aluminium extrusion rate is high.
The method of deviating from of impurity aluminum is in the rosin of the present invention: deviating from being produced in the rosiny process by the rosin raw material of aluminium carries out in the rosin.The rosin raw material is inserted in the acidic aqueous solution, and heating and under the effect of dealumination agent is behind the stirring reaction, after filtration, leave standstill clarification, separation, distill and obtain aluminium rosin product.
Described acidic solution can adopt sulfuric acid, hydrochloric acid or nitric acid to regulate, and control pH value of solution value is between 1～5.
Described dealumination agent is citric acid, Trisodium Citrate, Tripotassium Citrate, ammonium citrate, EDTA, Sodium Fluoride, Neutral ammonium fluoride, sulphosalicylic acid, tartrate or Seignette salt.
Described Heating temperature is 50～90 ℃.
The concentration of the described dealumination agent aqueous solution is 0.5～1%, the rosin raw material: water is 1:1.
0.5～1.0 hour described stirring reaction time, stirring velocity 300～600rpm.
Describedly leave standstill that temperature is controlled between 50～90 ℃ in the clarifying process.
The present invention is achieved in that it is in 1～5 acidic solution that a certain amount of rosin raw material is joined the pH that contains dealumination agent, be warming up to 50～90 ℃, under the condition of low whipping speed 300～600rpm, behind reaction 0.5～1.0h, filtered while hot, remove the coarse impurities such as pine branch that mixed system is mingled with, leave standstill certain hour at 80～90 ℃ then, after treating the material layering clarification, water is separated with fat liquid organic phase, and filtering fat liquid with 80 eye mesh screens, the fat liquid that leaches adopts steam distillation that turps is separated with rosin in three mouthfuls of matrasss of band prolong, obtains turps and dealuminzation rosin product respectively.In the rosin of this invention impurity aluminum deviate from production technique, with the rosin raw material with the acidic aqueous solution that contains dealumination agent under heating, stir process is filtered then, fat liquid separates through leaving standstill clarification, steam distillation obtains containing the rosin product of aluminium less than 10ppm.
It is simple that this technology has treating processes, and the treatment time is short, processing ease, safety, and characteristics such as equipment is simple are easy to realize suitability for industrialized production.Because this invention production unit cost is low, therefore excellent performance has the very strong market competitiveness and application value.
