| titleOfInvention | Method for large-scale extraction of l-quebrachitol from natural rubber industry waste water |
| abstract | Provided is a method for large-scale extraction of L-Quebrachitol from natural rubber industry waste water, the method comprising the following steps: coarsely filtering the natural rubber industry waste water to obtain a waste water clear-liquor (A); filtering the waste water clear-liquor (A) with an ultrafiltration membrane to obtain a filtrate (B); concentrating the filtrate (B) with a nanofiltration membrane or a reverse osmosis membrane to obtain a concentrated solution (C); decolorizing, evaporating and concentrating the concentrated solution (C) to obtain a pasty concentrated solution (D); cooling and crystallizing the pasty concentrated solution (D), and collecting the crystals to obtain a coarse product (E); and purifying the coarse product (E) to obtain a pure L-Quebrachitol. The method has a simple technical process and low cost, and can be produced on a large scale with 99% purity for the obtained product. |
