We are offering ethyl acetate.Ethyl acetate is a colorless liquid with a fruity odour, having a molecular weight of 88.10. It is slightly soluble in water and soluble in most organic solvents, such as alcohol, acetone, ether and chloroform. Ethyl acetate is used primarily as a solvent and diluent, being favored because of its low cost, low toxicity, and agreeable odor. For example, it is commonly used to clean circuit boards and in some nail varnish removers (acetone and acetonitrile are also used).

We are offering calcium nitratem, 'calcium nitrate, also called norgessalpeter (norwegian saltpeter), is the inorganic compound with the formula ca(no3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns. A variety of related salts are known including calcium ammonium nitrate decahydrate and calcium potassium nitrate decahydrate use: use in fertilizer as of 1978, only 170, 000 tonsyear were produced for applications in fertilizers. The fertilizer grade (15.5-0-0 + 19% ca) is popular in the greenhouse and hydroponics trades; it contains ammonium nitrate and water, as the "double salt" 5ca(no3)2.nh4no3.10h2o. This is called calcium ammonium nitrate. Formulations lacking ammonia are also known: ca(no3)2.4h2o (11.9-0-0 + 16.9?). A liquid formulation (9-0-0 + 11% ca) is also offered. An anhydrous, air-stable derivative is the urea complex ca(no3)2.4[oc(nh2)2], which has been sold as cal-urea. waste water treatment calcium nitrate is used in waste water pre-conditioning for odour emission prevention. The waste water pre-conditioning is based on establishing an anoxic biology in the waste water system. In the presence of nitrate, the metabolism for sulfates stops, thus preventing formation of hydrogen sulphide. Additionally easy degradable organic matter is consumed, which otherwise can cause anaerobic conditions downstream as well as odour emissions itself. The concept is also applicable for surplus sludge treatment. concrete calcium nitrate is used in set accelerating concrete admixtures. This use with concrete and mortar is based on two effects. The calcium ion accelerates formation of calcium hydroxide and thus precipitation and setting.
