文摘
- •
HCB is completely destroyed by CaC2 within 20 min via mechanochemical treatment.
- •
CaC2 shows much higher reactivity than traditional alkaline co-milling regents.
- •
HCB is converted to nonhazardous CaCl2 and carbon materials.
- •
HCB is destroyed via nucleophilic substitutions of C-Cl by alkynyl in CaC2.
