Synthese

The raw material methyl ether liquid was pumped to the molecular sieve adsorption tower, and passed upward through the molecular sieve bed from the lower part of the molecular sieve adsorption tower with a residence time of 30 minutes. The adsorption process was carried out at 0.5MpaG and 0. After molecular sieve adsorption treatment, the water content in the refined methyl ether is reduced to 0.001%. The raw material boron trifluoride gas enters the low-temperature distillation tower, and the temperature at the top of the tower is controlled at -105C, and the pressure is controlled at O.1MpaG. After the distillation process, the refined boron trifluoride comes out from the top of the tower without hydrogen fluoride, silicon tetrafluoride and other impurities.

Refined methyl ether flows through the column tube of the complex reactor from the top to the bottom, and the refined boron trifluoride gas enters the column tube of the complex reactor from the bottom to the top, and the methyl ether and boron trifluoride undergo the complexation reaction on the packing of the column tube. The complexation reaction was controlled at 0.6 MPaG and the temperature was controlled at -10. The generated complex was pumped to the exchange reaction distillation column. The vacuum of the exchange reaction distillation column was 150 mmHg, the temperature at the top of the column was 85C, and the temperature of the kettle was 90C. Eventually, after the exchange reaction and distillation equilibrium were reached in the exchange distillation column, boron trifluoride-11 gas with more than 99% abundance was obtained from the top of the tower, and boron trifluoride methyl ether-10 isotope product with more than 95% abundance was obtained from the tower kettle.
mögliche Exposition
Used as a catalyst.
Erste Hilfe
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water ormilk. Do not induce vomiting. Medical observation isrecommended for 24 48 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for pulmonaryedema,a doctor or authorized paramedic may consideradministering a corticosteroid spray.
Lager
Color Code—Red: Flammability Hazard: Storein a flammable liquid storage area or approved cabinetaway from ignition sources and corrosive and reactivematerials. Before entering confined space where thesechemicals may be present, check to make sure that anexplosive concentration does not exist. Store in tightlyclosed containers in a cool, well-ventilated area. Metalcontainers involving the transfer of this chemical shouldbe grounded and bonded. Where possible, automaticallypump liquid from drums or other storage containers toprocess containers. Drums must be equipped with selfclosing valves, pressure vacuum bungs, and flame arresters.Use only nonsparking tools and equipment, especiallywhen opening and closing containers of this chemical.Sources of ignition, such as smoking and open flames, areprohibited where this chemical is used, handled, or storedin a manner that could create a potential fire or explosionhazard.
