Ya!ψ(`∇´)ψ RM po reakcii benzaldehyd + MEK + HCI sčernel a vyznieva ako výzva na destiláciu 3-metyl-4-fenyl-3-butén-2-ónu s bodom varu 269! Prvýkrát som si kúpil vákuovú pumpu -60 kpa na vákuovú dekompresiu a úspešne som získal zlatožltú kvapalinu 3-Metyl-4-fenyl-3-butén-2-ón! Zdá sa však, že stroj je prehriaty. Teraz môžem destiláciu len pozastaviť... Chcete, aby sa zvyšný rm úplne vydestiloval, však? Nechcem predestilovať nečistoty s vyšším bodom varu a zničiť si tak ťažkú prácu⋯.

Pls show your vacuum pump and how you used it in distillation please.

Now looking back at the pump I used at that time, I was able to use ultra-high temperature to evaporate and distill out a product with a boiling point of 260 degrees. It was incredible. I remember that the thermometer showed about 220 degrees. You must not do what I did. I suggest you buy an oil-driven vacuum pump and test the glass interface for high-vacuum silicone. Also pay attention to safety during the application process!
