WebFunctionalized carbon nanofibers (CNF) are fascinating materials to be used as supports in Pd-based catalysts for the treatment of waste chloroform (TCM) to produce light olefins through the catalytic hydrodechlorination (HDC). The CNF were functionalized by HNO3, HCl, and urea. Compared to the Pd supported on un-treated CNF, all the catalysts using … WebCollagen. Collagen is the most abundant protein in the body. Its fiber-like structure is used to make connective tissue. Like the name implies, this type of tissue connects other tissues and is a major component of bone, skin, muscles, tendons, and cartilage. It helps to make tissues strong and resilient, able to withstand stretching.

WebIn general, chloroform production can be increased by increasing the chlorine/methane ratio and varying operating temperatures (Versar 1977). In 1978, 158,500 kkg of chloroform were produced in the United States. This represents 71 percent of the production capacity. WebChloroform is primarily used in the production of refrigerants (e.g. chlorofluorocarbon (CFC)-22, fluorocarbon-22), in the production of plastics (especially vinyl chloride) and … Industrially, chloroform is produced by heating a mixture of chlorine and either methyl chloride (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 + … See more Chloroform, or trichloromethane (often abbreviated as TCM), is an organic compound with the formula CHCl3 and a common organic solvent. It is a very volatile, colorless, strong-smelling, dense liquid produced on … See more The molecule adopts a tetrahedral molecular geometry with C3v symmetry.
