Ball milling of calcium carbide (CaC 2) enables the reaction of its ethynyl moiety with organic electrophiles.This was realized simply by co-milling CaC 2 with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing α-hydrogens were ethynylated in good yields at short reaction times.

The invention relates to a method for synthesizing a carbyne nano-material from calcium carbide and polyhalohydrocarbon as raw materials through ball-milling and belongs to the field of preparation of novel carbon nano-materials. The method is characterized by comprising the steps: adding the calcium carbide and the polyhalohydrocarbon, which serve as the raw materials …

Calcium carbide. 1. Introduction. ... During the ball milling, the peak intensity of organic chlorine weakened slightly at 6 h, and disappeared completely at 12 h, which indicates that the mechanochemical reaction is mainly taken place in the second 6 h, ...

For subsurface injection, a powdered carbide is manufactured by ball milling selected sizes of carbide to less than 140 US-mesh (<105 microns). The milled carbide can then be custom blended with a wide range of other powder additives, such as lime, limestone, and fluorspar to meet customer specified formulations.

We have ground calcium carbide in the past and it has worked fairly well. We have a number of different mill sizes ranging to 15 mtph. Our mill is very energy effiecent and requires no special foundations. Currently we are grinding the zeolite to under 20 microns. But our mill can easily be adjusted to grind from grit size to under 5 microns.

11.4 Calcium Carbide Manufacturing 11.4.1 General Calcium carbide (CaC2) is manufactured by heating a lime and carbon mixture to 2000 to 2100°C (3632 to 3812°F) in an electric arc furnace. At those temperatures, the lime is reduced by carbon to calcium carbide and carbon monoxide (CO), according to the following reaction: CaO+3C→CaC2 +CO
