CH 3 CH 2 OH + Cl 2 CH 3 CHO


In Dictionary of Chemistry (2002: Balai Pustaka) chloroform is a colorless liquid with a sweet odor, pleasant and anesthetics. In daily life serves as a tranquilizer chloroform, and the organic compound solvent.
According Riawan (1990), chloroform (CHCl 3) can be used for fat solvent, "dry cleaning", dope. For drug use spiked with ethanol, stored in brown bottles, filled to the brim.
Chloroform can be made via the electrophilic substitution cristalizacion reaction H atoms ά all carbonyl compounds bergugus acetyl (CH 3 CO-) in alkaline conditions. Materials can also be used when the alcohol is oxidized generating an acetyl group.
Chloroform was originally used in medicine as a anastesik. However, chloroform is easily oxidized cristalizacion in the presence of air and light into posgen or carbonyl chloride COCl 2 is dangerous.
In addition, chloroform cristalizacion and some other compounds containing group metilkloro,-CCl 3 shows a strong physiological effects, such as trikloroasetaldehida, or chloral hydrate, Cl 3 CCH (OH) 2, and trichloro-tert-butanol or kloretone, Cl 3 C ( CH 3) 2 OH to give hypnotic effect.
In industry, chloroform is obtained by heating a mixture of chlorine and chloro methane or metan.Pada temperature of 400-500 C free radical halogenation. In the manufacture or synthesis of chloroform to note a few things: the presence of oxygen from the air and sunlight cristalizacion can be oxidized with chloroform then slowly becomes phosgene (highly toxic gas).
CH 3 CH 2 OH + Cl 2 CH 3 CHO
While the reaction cristalizacion with acetone is stronger, so that the synthesis process used a somewhat different composition tool. Reaction is as follows:
2. Haloform namely multi halogenated or haloform reaction occurs at the carbon cristalizacion atom of the methyl cristalizacion group. Haloform occurred cristalizacion because the halogen substitution of the first to make the rest of the α-hydrogens on the carbon metillebih acid. Finally, proton transfer occurs carboxylic acids and positive ions or the haloform.
Chloroform haloalkane compound is a compound that binds to three halogen atoms chlorine (Cl) on its C chain. Chloroform compounds can be made with basic ingredients such as organic compounds having a methyl group (-CH 3) attached to the C atom of the carbonyl or hydroxy C reagent reacted with halogens (Cl 2). Halogenated often run in explosive and almost without exception produces a mixture of products, because this is a halogenated welds sometimes be used in the laboratory. cristalizacion
I am currently a student at the University of Diponegoro. cristalizacion I shy person who just loves to write. but actually I was brave to aspire. I am not like to wait and wait. I always wanted cristalizacion to change and I tried to be successful with all the dreams View my complete profile
