Usage

Chemical Properties

bluish green crystal(s) [STR93]

General Description

A green to blue odorless powder. Insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Cupric tartrate is noncombustible. Used for electroplating metals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Acidic salts, such as Cupric tartrate , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Health Hazard

INHALATION: Inhalation of dust may cause nasal congestion. EYES: May cause conjunctivitis and edema of eyelids. SKIN: May irritate skin. INGESTION: Vomiting is caused by local irritant and astringent action of ionic copper on stomach and bowel.

Effects of the size of nano-copper catalysts and reaction temperature on the morphology of carbon fibers

In this study, carbon fibers with different morphologies, including coiled carbon nanofibers and straight carbon fibers, were obtained by the chemical vapor deposition using a Cu-catalytic pyrolysis of acetylene at 250 °C. The influences of nano-copper catalyst particle size and the reaction temperature on the morphology of carbon fibers were investigated. Under the same reaction condition, coiled carbon nanofibers generally were synthesized using nano-copper catalyst with smaller particles size, and bigger copper particles are apt to produce straight carbon fibers. With decreasing of reaction temperature to 200 °C, straight carbon fibers were obtained, instead of coiled carbon nanofibers at 250 °C. The product was characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and X-ray powder diffraction (XRD).

Effect of synthesis method of nanocopper catalysts on the morphologies of carbon nanofibers prepared by catalytic decomposition of acetylene

Carbon fibers, prepared by metal-catalyzed decomposition of hydrocarbons, e.g., acetylene, benzene, and methane, present various growth models including whisker-like, branched, bi-directional, and multidirectional types of growth. The addition of additives or a second metal to the metal catalyst, the use of a support, the pretreatment of the catalyst, and the catalyst source may have considerable effects on carbon deposition. Carbon nanofibers were synthesized by the decomposition of acetylene with nanocopper catalysts to determine the effects of synthesis method on the morphologies of carbon nanofibers obtained. Copper nanoparticles catalyzed the carbon deposition of acetylene to yield regularly coiled fibers with a novel symmetric growth type, whereas ribbon-like fibers formed over nanocopper particles prepared by hydrogen-arc plasma method. The copper nanocrystals changed from irregular or spherical shape to faceted shapes after fiber growth. The regularity of the shapes of the faceted catalyst particles included in the fibers accounted for the different morphologies of the resulting products.
