Chloroform 18.08.2020.Pdf
Chloroform Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, sweet-smelling, dense liquid that is produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is one of the four chloromethanes and a trihalomethane. It is a powerful anesthetic, euphoriant, anxiolytic and sedative when inhaled or ingested. Formula: CHCl₃ IUPAC ID: Trichloromethane Molar mass: 119.38 g/mol Boiling point: 61.2 °C Density: 1.49 g/cm³ Melting point: -63.5 °C The molecule adopts a tetrahedral molecular geometry with C3v symmetry. Chloroform volatilizes readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow. Chloroform does not significantly bioaccumulate in aquatic organisms. Production:- In industry production, chloroform is produced by heating a mixture of chlorine and either chloromethane (CH3Cl) or methane (CH4). At 400–500 °C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl CH2Cl2 + Cl2 → CHCl3 + HCl Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): CHCl3 + Cl2 → CCl4 + HCl The output of this process is a mixture of the four chloromethanes (chloromethane, dichloromethane, chloroform, and carbon tetrachloride), which can then be separated by distillation. Chloroform may also be produced on a small scale via the haloform reaction between acetone and sodium hypochlorite: 3 NaClO + (CH3)2CO → CHCl3 + 2 NaOH + CH3COONa Deuterochloroform[ Deuterated chloroform is an isotopologue of chloroform with a single deuterium atom. -

CHEMICAL STORAGE SEGREGATION GUIDELINES Incompatible Chemicals Should Always Be Handled and Stored So That They Do Not Accidentally Come in Contact with Each Other
Laboratory Safety Reminders January 2007 ♦ Mount Holyoke College – Environmental Health and Safety CHEMICAL STORAGE SEGREGATION GUIDELINES Incompatible chemicals should always be handled and stored so that they do not accidentally come in contact with each other. This list is not complete, nor are all compatibilities shown. These materials can react to produce excessive heat, harmful vapors, and/or other deadly reactions.

The process activation energies, the order and the rate constant of the conversion reaction as well as kinetic values of the reagent consumption are determined depending on temperature, time and carrying conditions of processes. The order of the conversion process of calcium chloride with sodium chlorate equals one. It is confirmed by the fact that the conversion rate constant calculated on the basis of experimental data remains practically constant for each temperature. Also, the linear dependence of lg (C0-Cτ) on τ also indicates the first order of the conversion process of calcium chloride with sodium chlorate. The rate constant of conversion increases with a rise in temperature. Its dependence on temperature obeys Arrhenius law. To establish values of the conversion rate constant for different temperatures, the constants (К0) for 20 and 25% solutions of calcium chloride have been calculated by Arrhenius equation and the dependence equation of lg K on 1 / T has been derived. -
