Commercial nitrification inhibitors (NIs), namely nitrapyrin, 3,4-dimethylpyrazol phosphate (DMPP) and dicyandiamide (DCD), are ineffective at high temperatures. Therefore, it is imperative to explore new compounds that can be commercialised as effective NIs for warm climatic conditions. The aim of the present study was to compare the potential of 4-amino-1,2,4-triazole (ATC) with the two ...

Carbide - Wikipedia

Several carbides are assumed to be salts of the acetylide anion C 2 2– (also called percarbide), which has a triple bond between the two carbon atoms. Alkali metals, alkaline earth metals, and lanthanoid metals form acetylides, e.g., sodium carbide Na 2 C 2, calcium carbide CaC 2, and LaC 2. Lanthanides also form carbides (sesquicarbides, see below) with formula M 2 C 3.

Calcium Carbide Applications - Carbide Industries LLC

Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
