Calcium Oxide

Calcium oxide is also called as quicklime or burnt lime. It is a widely used chemical compound. Calcium oxide is a white, caustic, alkaline, crystalline solid at room temperature. Calcium oxide is usually made by the thermal decomposition of materials such as limestone, or seashells, that contain calcium carbonate in a lime kiln.It is prepared by heating calcium carbonate in a special lime kiln to about 500°C to 600°C, decomposing it into the oxide and carbon dioxide. Calcium oxide is widely used in industry.Calcium oxide is a basic anhydride, reacting with water to form calcium hydroxide.

Carminic Acid

Carminic acid is a red glucosidal hydroxyanthrapurin that occurs naturally in some scale insects, such as the cochineal and the Polish cochineal. The insects produce the acid as a deterrent to predators. The chemical structure of carminic acid consists of a core anthraquinone structure linked to a glucose sugar unit. It is used as coloring agent in food, cosmetics and meications. It is also used as histologic stains for biological materials.

Properties Suppliers
Ceric Sulfate

The ceric ion is a strong oxidizer, especially under acidic conditions. If ceric sulfate is added to dilute hydrochloric acid, then elemental chlorine is formed, albeit slowly. With stronger reducing agents it reacts much faster. Ceric sulfate is used in analytical chemistry for redox titration, often together with a redox indicator.

Diethyl Ether

Diethyl Ether was first synthesized in 1540 by Valerius Cordus, and he termed as - sweet oil of vitriol. Diethyl ether is an extremely flammable organic solvent with many uses. Diethyl ether was one of the first anesthetics developed for surgical use, but has since been replaced by less flammable chemicals. Diethyl ether is commonly used as an industrial or laboratory solvent. It has narcotic properties and has been known to cause temporary psychological addiction, sometimes referred to as etheromania. Diethyl ether is particularly important as a solvent in the production of cellulose plastics such as cellulose acetate, fats, waxes, resins and similar substances. Diethyl ether has a high cetane number of 85-96 and is used as a starting fluid, in combination with petroleum distillates for gasoline and diesel engines. It is a common laboratory solvent. It is also a common solvent for the Grignard reaction in addition to other reactions involving organometallic reagents,liniments and analgesics (painkillers) and smokeless gun powder. It is also used in agricultural and pharmaceutical applications, as an intermediate in the preparation and manufacturing of other basic organic chemicals, as a catalyst in industrial polymerization processes, as an alternative fuel, as a foam expansion agent, and as an aerosol propellant for a variety of products that include adhesives, sealants, foam in a can, coatings, paints, automotive care products, topical skin cooling sprays, over the counter treatments, hairspray, sun screen and a variety of other personal care and household products. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis.
