accompanies Indy? What type of fuel these vehicles use? Studies have shown that vehicles using methyl alcohol or methanol produce less polluting than other fuel powered. However, there are some Disadvantages in the use of methanol. One is the difficulty in handling due to the high toxicity of this substance, the other is that during the burning of the flame is virtually invisible methanol, which can cause serious accidents. Furthermore, there is evidence that the methanol combustion residues are carcinogenic, which requires caution in using a large scale. Thus, the trend is that the meta- nol be used only as an additive to other fuels. The use of methanol in beverages is prohibited, because it is a highly toxic compound that causes blindness and even death. This alcohol is used as a solvent for paints and varnishes, as a fuel feedstock in obtaining the formaldehyde and also in perfumery (gets its name from the colonial essence). As we have seen in the reaction of the breathalyzer, an alcohol, in case the Etam hyde acetaldehyde or acetic acid), is the first substance in the alcohol ethyl becomes our body when we ingest alcoholic beverages. The ethanal is the one responsible for the nausea and headache caused by the exaggerated consumption of alcoholic beverages. As aldehydes, ketones - another group of oxygenated functions - have a similar called carbonyl group (C The simpler substance is known as acetone, also bears the name of propanone and dimethyl ketone. It is a substance well known for its use as a solvent to remove nail polish. Presents as a colorless liquid with an agreeable odor, very volatile and miscible with water. Its application in industry is as a solvent for paints, varnishes, enamels, etc.. It is also used in the preparation of artificial silk, celluloid, smokeless powder, dyes, medicines, etc.. Being a key reagent in laboratories refining cocaine, acetone has its marketing subsidiary of the Federal Police. With respect to oxidation, aldehydes are oxidized with potassium permanganate in acid medium, while ketones are not oxidized.

prati Indy? Koja vrsta goriva te vozila koriste? Istraživanja su pokazala da su vozila na metilnog alkohola metanola ili proizvode manje zagađuje od drugih goriva napaja. Međutim, postoje neke Nedostaci u korištenju metanola. Jedan je poteškoća u rukovanju zbog visoke otrovnosti ove tvari, a druga je da je za vrijeme požara u plamenu je gotovo nevidljiva metanola, koji može dovesti do ozbiljnih nesreća. Nadalje, postoje dokazi da su metanol ostataka izgaranja su kancerogeni, što zahtijeva oprez u korištenju velikih razmjera. Dakle, trend je da je meta- Nol se koristiti samo kao dodatak drugim gorivima. Korištenje metanola u liker je zabranjeno, jer je to vrlo otrovna tvar koja uzrokuje sljepoću, pa čak i smrt. Ovaj alkohol se koristi kao otapalo za boje i lakove, kao gorivo kao sirovine u dobivanju formaldehid i također u parfumeriji (dobiva svoje ime iz kolonijalnog suštini). Kao što smo vidjeli u reakciji na breathalyzer, alkohola, u slučaju Etam Hyde acetaldehid ili octena kiselina), je prva tvar u alkoholu etilni postaje naše tijelo kad smo gutati alkoholna pića. Ethanal je osoba odgovorna za mučninu i glavobolju uzrokovanu pretjeranom konzumacijom alkoholnih pića. Kao aldehidi, ketoni - jedna skupina kisikom funkcija - imati sličan tzv karbonilnu skupinu C ( O). Jednostavnije tvar poznata kao aceton , također nosi ime propanone i dimetil ketona. To je tvar poznata po svojoj uporabi kao otapala za uklanjanje laka za nokte. se predstavlja kao bezbojna tekućina s ugodnim mirisom, vrlo nestabilnim i miješa se s vodom. Njegova primjena u industriji kao otapalo za boje, lakovi, emajla, itd.. Također se koristi u izradi umjetne svile, celuloid, bezdimni prah, boja, lijekova, itd.. Budući da je ključna reagensa u laboratorijima preradi kokaina, acetona ima svoje marketinške podružnica Savezne policije. S obzirom na oksidaciju, aldehidi oksidiraju s kalij permanganata u kiselom mediju, a ketoni ne oksidira.
