Preparation of 3-DECANOL
1. Add 200 grams of 3-decanone and 0.359 grams of [RuHCl(CO)(NNHPiPr2)] to a 500-ml autoclave successively, close the autoclave, and feed hydrogen into the autoclave twice to replace the original air in the autoclave ; After the replacement, 2.5 MPa of hydrogen gas was passed into the autoclave, and the reaction was carried out at 30° C. for 8 hours;
2. After the end, cool the reaction system to room temperature, discharge the remaining hydrogen, open the autoclave, and transfer the reaction solution to a 500 ml three-port still, and install a 20-plate rectifying still on the still. Column, evacuate to 0.095MPa, heat the distillation still, so that the still temperature rises gently from room temperature to 160 ° C, when there is reflux at the top of the column, control the reflux ratio to 2.0, collect and obtain 0.6 g of 80 ~ 100 ° C distillate, decanone Content is 99%, 1.5 grams of 100～120 ℃ fraction, the content of 3-n-decanol is 82%, 120～140 ℃ fraction 195.4 grams, the content of 3-DECANOL is 99%, 2.0 grams of raffinate in the kettle, 3- DECANOL content is 99%;
3. Add 192 grams of decanone, transfer the added feed liquid to the autoclave again, repeat steps 1 and 2, and the yield of decanol is 98.7%. This synthetic method has the following advantages:
(1) Decanol is prepared by hydrogenation, which has the advantages of environmental friendliness and simple post-treatment;
(2) The catalyst consumption in the method is less, the product yield is high, and the catalyst can be reused, thereby greatly reducing the production cost; in addition, the catalyst recycling method is also very simple and easy to realize;
(3) The product is separated by vacuum distillation, which can achieve higher purification of the product, and only needs to be separated by rectification once, and the product content can reach more than 98%, thereby reducing the separation cost.
3-DECANOL Split Method
In the field of stereoisomerism, considerable progression has actually been made recently in racemization, the conversion of optical isomers into their counterparts, to get racemic mixtures, as well as deracemization precise reversal of the spin treatment. Although in the case of sterically labile substances, such as cyanohydrins, hemi(thio)-acetals, α-substituted carbonyl substances, and α-substituted hydantoins, the Base catalysis attains racemization, but sterically stable substances, such as additional alcohols as well as chiral amines, are much more challenging to racemize.
CN200980111538.7 Chemical deracemization of a mixture of enantiomers of a second alcohol by a mix of oxidation and decrease responses through a stereoselective alcohol dehydrogenase and also its cofactor, where one enantiomer of the optically active additional alcohol The isomeric form is selectively oxidized to the matching ketone, which is then selectively minimized to the optical antipodes while providing the lower kind of the cofactor to the decrease response by an additional enzyme. The approach according to the creation is defined because 2 alcohol dehydrogenases with contrary stereoselectivities and also different cofactor selectivities, and also two matching various cofactors, are utilized for the oxidation as well as decrease reactions, and the oxidized and also minimized The cofactors of are interconverted in identical enzymatic responses making use of added enzymes, and also the direction of deracemization can be controlled in the direction of both enantiomers by the choice of two alcohol dehydrogenases or by the distinction in selectivity for both cofactors utilizing extra enzymes. One of the isomers.
3-DECANOL Through the approach according to the invention, it is feasible to accomplish deracemization with considerably quantitative optical yields, ie > 99% ee.
How to Operate 3-DECANOL
ADH-A, LK-ADH, NADP-specific FDH (2IE), ammonium formate (substrate concentration 3eq.), NAD+ and NADP+ (substrate, 3mol%) were suspended in TRIS-HCl (50mM, pH7. 5, total volume 0.5ml). The reaction was started by adding racemic 3-n-decanol (0.5 [mu]l, 8 mmol/ml, ee<3%). After shaking (130 rpm) at 30°C for 3 h, the mixture was extracted with EtOAc (500 μl) and centrifuged to produce a phase separation.
