In the aromatic compounds of carbon-carbon bonds own way parameters usually occupy an intermediate position mezhdusvyazyami C-C and C = C. They differ in a large variety of these limits, whereby many organic compounds of the formula shown in the form of systems with alternating single and double carbon-carbon bonds, have significant drawbacks.
Higher liquid and solid alcohols
primary alcohols containing 6-10 carbon atoms, branched alcohols and many with much higher molecular weight are liquid. Most of these alcohols can be prepared synthetically, only, but several of them occur in nature in the essential oils in the form of esters.
Reactions acetoacetic ester
From the numerous reactions acetoacetic ester, specify the following, the most typical: 1. Hydrogen reduction. When restoring acetoacetic ester with hydrogen in statu nascendi obtained β-hydroxy acid: 2. The action of hydrocyanic acid.
The amino alcohols
The simplest aminoalkogoli aminoalcohols, hydroxyamines contain, besides one or more hydroxyl group, another amino group, the latter may be a primary, secondary or tertiary, as shown by the following formulas: By addition of alkyl halides to tertiary amino alcohols can form s alts of the corresponding quaternary ammonium bases, such as iodide s alt [HO-CH 2 CH 2 -NCH 3 3 ] J. The simplest amino alcohols are primary products of the addition of ammonia to aldehydes The most studied aminoalcohols contain a hydroxyl and an amino group on adjacent carbon atoms, β-aminoalcohols.
Dibasic triatomic hydroxy acids. Tartronic acid and yablocheaya
The simplest of the dibasic acid hydroxy acids is oksimalonovaya SNONSOON 2 , called tartronic. It can be obtained from bromomalonic acid under the influence of her wet silver oxide and acid recovery mezoksalevoy SOSOON 2 . Tartronic acid-a crystalline substance with m. Pl. 187 & deg; C. The melting it cleaves carbon dioxide and release water turns into polymers partially glycolide.
