Preparation method for montanin wax resin distillate

Abstract

The invention discloses a preparation method for montanin wax resin distillate, belonging to the technical field of agricultural chemistry. The preparation method is a process for preparing a distillate from montanin wax resin through oxidation, degradation, evaporation, concentration, condensation and the like and is a novel approach for conversion of the waste into the valuable and high-efficiency utilization of montanin wax resin. The prepared distillate has good effect on improved breeding of sprouts, yield increase of crops, etc., and shows the characteristic of extremely high activity under the condition of extremely low content of effective substances; and the distillate has substantial advantages in development of high-end products of montanin wax resin, improvement of product benefits and the like, shows immense market prospects, and is free of toxicity and pollution and flexible and convenient to use. Moreover, the preparation method is simple in process flow, decreased in energy consumption, friendly to environment, high in production efficiency, good in safety and operability, low in cost, and easy to promote.

Description

technical field [0001] The invention relates to a preparation method of montan wax resin distillate, which belongs to the technical field of agricultural chemistry. Background technique [0002] Montan Wax is a rare mineral extracted from lignite, peat and other young coals with organic solvents. It is also called montan wax or peat wax due to different sources. Montan wax resin refers to the general name of resin components in montan wax. In the field of montan wax technology, the crude montan wax is generally divided into three basic components: pure wax (about 60-70%), resin (about 20-30%) and bitumen (about 5- 10%); pure wax belongs to the "active ingredient" in the processing and utilization of montan wax, while resin and asphalt are regarded as "harmful ingredients" that hinder its performance, especially the high content of resin makes its impact particularly prominent; therefore , in order to give full play to the excellent properties of montan wax, it is usually n...

Problems solved by technology

[0004] Although the above-mentioned two patent texts have disclosed the method of oxidative degradation of montan wax resin, there are still great limitations in view of the research level and experience level at that time

For example, although an auxiliary solvent was used to improve the dispersibility of the resin, the type and ratio of the auxiliary agent were not screened and optimized to the greatest extent, so the degree of effective reaction and its scope were not optimal; The problem of oxidant residue and desalination technology is not good enough. In the selection of oxidants, inorganic oxidants with higher oxidation activity and better effect are directly excluded. Now the problems of oxidant residue and desalination have been solved, making inorganic oxidants an option. ; The above two factors have greatly affected the yield of degradation products and the type and quantity of active ingredients
