Calcium Carbonate

Calcium carbonate is a chemical compound. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. It is the active ingredient in agricultural lime, and is usually the principal cause of hard water. Calcium carbonate is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous. The main use of calcium carbonate is in the construction industry. It is used in the oil industry in drilling fluids as a formation bridging and filtercake sealing agent and may also be used as a weighting material to increase the density of drilling fluids to control downhole pressures. It is widely used as an extender in paints and as a filler in plastics. It is also used in adhesives, sealants, and decorating fillers. Calcium carbonate is a common ingredient for many glazes/ceramics in its white powdered form.

Chloroacetic Acid

Chloroacetic acid is the organochlorine compound. Chloroacetic acid is prepared industrially via two routes. The predominant method involves chlorination of acetic acid, with acetic anhydride as a catalyst. Chloroacetic Acid is converted to chloroacetyl chloride, a precursor to adrenaline (epinephrine). Chloroacetic acid is easily soluble in water, soluble in alcohol, methanol, acetone, carbon, disulphide, benzene, chloroform, ether. Chloroacetic Acid is an intermediate for the production of pesticides like 2,4-D acids (2,4-dichlorophenoxyacetic acid), Dimethoate, CAC (Chloroacetyl chloride), TCAC (Trichloroacetyl chloride), 2,4,5-T acid (2,4,5-Trichlorophenoxyacetic acid), MCPA (2-methyl-4-chlorophenoxyacetic acid), glyphosate (N-(phosphonomethyl) glycine).Chloroacetic acid is used in the production of ibuprofen/brufen, dichlophenac sodium, caffeine, vitamins, glycine, N-(P-hydroxyphenyl)-glycine (METOL), maleanates. Chloroacetic Acid is converted to chloroacetyl chloride, a precursor to adrenaline (epinephrine). Chloroacetic Acid is used in manufacturing a variety of products including herbicides and pharmaceuticals, anesthetics, tranquilizers and amphoteric surfactants, which are cleansing agents used in shampoos.

Chromium Trioxide

Chromium trioxide is the acidic anhydride of chromic acid. It is mainly used in chrome-plating. Typically it is employed with additives that affect the plating process but do not react with the trioxide. The trioxide reacts with cadmium, zinc, and other metals to generate passivating chromate films that resist corrosion.

Copper Dichloride

Copper dichloride is a chemical compound. A major industrial application for copper dichloride is as a co-catalyst with palladium(II) chloride in the Wacker process. It catalyzes the chlorination in the production of vinyl chloride and dichloroethane. It has a variety of specialized applications in the synthesis of organic compounds. It effects chlorination of aromatic hydrocarbons- this is often performed in the presence of aluminium oxide. It is able to chlorinate the alpha position of carbonyl compounds. It is also used in pyrotechnics as a blue/green coloring agent. In a flame test, copper chlorides, like all copper compounds, emit green-blue.

Hexafluorobenzene is an organic, aromatic compound. In this derivative of benzene all hydrogen atoms have been replaced by fluorine atoms. The technical uses of the compound are limited, although it is recommended as a solvent in a number of photochemical reactions. In the laboratory hexafluorobenzene is used for several purposes.

Hydrochloric Acid

Hydrochloric acid is a solution of hydrogen chloride in water, that is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid. Hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride for PVC plastic.

Hydrofluoric Acid

Hydrofluoric acid is a solution of hydrogen fluoride in water. It is a valued source of fluorine, being the precursor to numerous pharmaceuticals such as fluoxetine and diverse materials such as polytetrafluoroethylene. It is a highly corrosive acid, capable of dissolving many materials, especially oxides. The principal use of hydrofluoric acid is in organofluorine chemistry. Most high-volume inorganic fluoride compounds are prepared from hydrofluoric acid. The ability of hydrofluoric acid to dissolve metal oxides is the basis of several applications. It removes oxide impurities from stainless steel, a process called pickling, and silicon wafers in the semiconductor industry. In similar manner, it is also used to etch glass. A 5% to 9% hydrofluoric acid gel is also commonly used to etch all ceramic dental restorations to improve bonding. For similar reasons, dilute hydrofluoric acid is a component of household rust stain remover and in car washes in "wheel cleaner" compounds. Diluted hydrofluoric acid is used in the petroleum industry in a mixture with other acids in order to stimulate the production of water, oil, and gas wells specifically where sandstone is involved.
