Embodiment 1

[0027] A post-processing method for synthetic borneol production. After the synthetic borneol raw material is prepared according to a conventional production method to obtain crude esters, the crude esters are washed with water, and then the washed crude esters are subjected to neutral steaming of light oil. For post-treatment, firstly adjust the pH value of the washed crude ester to 7±2 by adding buffer solution, and then distill the light oil; while the waste acid water (including oxalic acid and boric acid) produced during the crude ester washing will be combined with the distilled Mix the oil sludge produced by the post-treatment of refined esters obtained after light oil, add 6 large bags (about 2.5 tons) of oil sludge according to a 5 cubic meter tank, and then add waste acid water, and make the pH value of the solution after adding waste acid water at 3 -6 or so, then add 3.1 kg of demulsifier (or add demulsifier according to the weight ratio of 3‰-7‰ of red oil that can...

Embodiment 2

[0035] A post-processing method for synthetic borneol production. After the synthetic borneol raw material is prepared according to a conventional production method to obtain crude esters, the crude esters are washed with water, and then the washed crude esters are subjected to neutral steaming of light oil. Carry out post-treatment, firstly add the aqueous solution containing borax to the crude ester after washing as a buffer solution, adjust the pH value to 7 ± 2 and then carry out steaming light oil treatment; and the waste acid water produced during crude ester washing (including Oxalic acid and boric acid) will be mixed with oil sludge, put into 4 large bags of oil sludge (about 1.7 tons), then add waste acid water to adjust the pH value to 5.5, and then add 1.8 kg of non-ionic active agent demulsifier (or according to the estimated red oil output Add demulsifier to 4‰-6‰ of the amount), raise the temperature to 90°C, stir for 30 minutes, and let it stand for 5-8 minutes t...

Abstract

A postprocessing method for synthetic borneol comprises the steps of preparing the raw materials of synthetic borneol to obtain raw ester according to a conventional production method, then washing the ester by water, postprocessing the washed ester through a light oil steaming method, mixing the waste water (including oxalic acid and boric acid) obtained by washing the raw ester and oil mud generated by postprocessing refined ester obtained by steaming the light oil, adding non-ionic surface active agent to be taken as a demulsifying agent, conducting oil-mud separation to obtain red oil, and postprocessing the waste water after the oil-mud separation so as to achieve the purposes of recycling and discharging after reaching the standard. If the boric acid content is too high, part of boric acid crystals can be separated out by cooling and crystallizing, so that mother liquor containing boric acid achieves the demanded index and then returns to be taken as a water source for washing the raw ester; and the boric acid crystals can return to be taken as the water source for washing the raw ester through a prepared buffer solution.

Description

technical field [0001] The invention relates to a process for producing chemically synthesized substances, in particular to a post-treatment process for synthesizing borneol, and belongs to the technical field of chemical substance production processes. Background technique [0002] Borneo, commonly known as borneol, is structurally a dicyclic terpene alcohol, so it is also called inlay alcohol. It is not only a precious traditional Chinese medicine, but also a woody spice, but only a very small number of plants have this resource for collection. Since the natural borneol is far from meeting the needs, turpentine was invented as the starting material, so Now most of them use synthetic borneol instead of natural borneol. The technology of artificially synthesizing borneol mainly uses turpentine as a raw material, and the mixture mainly composed of α-pinene and β-pinene extracted from turpentine has a wide range of reliable sources. It is indeed a kind of synthetic borneol to...
