Other companies, in need of short-term workers, contract with the temporary work agency to send temporary workers, or temps, on assignments to work at the other companies. Temporary employees are also used in work that has a cyclical nature, requiring frequent adjustments to staffing levels.
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process. It also takes place in some species of fish where it provides energy when oxygen is scarce. Ethanol fermentation has many uses, including the production of al
Ethanol, C2H5OH, reacts with organic acids to form esters. Halogenation or Substitution of Ethanol with PCl5. Ethanol reacts with phosphorus pentachloride at room temperature to form hydrogen chloride, ethyl chloride (i.e. chloroethane) and phosphoryl chloride.One mole of ethanol loses one mole of water). When ethanol is mixed with concentrated sulphuric acid with the alcohol in excess and heated to 140 degC, diethyl ether distils over (two moles of ethanol loses one mole of water) .
