General description

Hydrazine monohydrochloride is commonly used as a reagent in the synthesis of pyrazoles.

Application

Hydrazine monohydrochloride has been used:
  • as catalyst in the synthesis of titanium oxide polymers via catalytic sol-gel process
  • in fabrication of amorphous titanium dioxide (TiO2) thin films exhibiting high refractive indices and high transparency
  • in preparation of ethyl 3-ethoxy-1H-pyrazole-4-carboxylate

Alginic acid is a suitable material for modification to prepare new derivatives because of presence of its carboxyl groups. The high content of carboxyl groups over the entire length of its chain renders it an easily modifiable material with a

Our program, which has focused on the preparation of new pyrazole derivatives, has led us to report here an original and simplified preparation of ethyl 3-ethoxy-1H-pyrazole-4-carboxylate. This is based on the reaction of hydrazine monohydrochloride and diethyl 2-(ethoxymethylene)malonate. Further transformations

Super adsorbent polymers can be considered to be a very efficient solution for wastewater treatment. In general, their adsorption capacities depend on the type and amount of the functional groups present on the surface of the polymers, while their economic

Titanium oxide polymers having a low-fractal dimension (d(f) < 2) were rapidly synthesized from titanium tetra-n-butoxide via a catalytic sol-gel process with a hydrazine monohydrochloride catalyst. Different from conventional sol-gel processes aimed at producing low-fractal dimension titanium oxide polymers, the
