The way to make something
There is a way to make something today, called "Ethyl 2 Triphenylphosphoranylidene Acetate". Its method is exquisite, and it is a clever technique of chemical industry.

To make this thing, you need to carefully select the raw materials, according to a certain order and appropriate ratio, and put them in a special device. In the meantime, the control of the heat and the length of time are all key.

Take an appropriate amount of raw materials first, and pour them carefully into the kettle. Heat slowly to make the things in the kettle react slowly. At this time, you can't take your eyes off, observe its color change, smell its gas turn, and know the process of the reaction. When the color is in a certain shape and the gas has a certain smell, cease fire to cool down.

Then, after several purification methods to remove its impurities and keep its essence. Or use filtration to separate solid and liquid; or use distillation to analyze its pure matter according to the difference in boiling point.

Finally get "Ethyl 2 Triphenylphosphoranylidene Acetate". This substance has good purity and can be used for other purposes. It has its value that cannot be ignored in the chemical industry.
