Synthesis and aminomethylation of oligoalkylphenol
A. I. AhmedovThe article is devoted to the synthesis and investigation of compounds of aminomethyl (Mannich base) obtained on the base of alkylphenol. With this purpose phenol is alkylated by hexene-1, to tell the truth, oligomerization of hexene-1 is conducted at the presence of phenol (as catalyst is used AlCl3). In this case phenol is alkylated by hexene-1 and by products of oligomerization hexеne-1. As the speed of reaction oligomerization is more than the speed of alkylation, the products of alkylation of fenol by oligomers exceed. The obtained oligoalkylfenol was investigated by the method of IR - spectroscopy. The synthesized oligoalkylfenol is subjected to reaction of aminomethylation with formation of Mannich base. With this purpose oligoalkylfenol is condensed with formaldehyde and dietylenetrianine simultaneously. The influence of synthesized compound on viscous-temperature properties of oil M-6 was investigated and it was shown that the addition of this compound oligoaminophenol allows to obtain base oils which correspond to the contemporary requirements by the means of viscosity index.Anticorrosive and detergent properties of 5% solution of oil M-6 were investigated and satisfactory results were obtained. So, multifunctional additives improving the viscous-temperature, detergent and anticorrosive properties of lubricating oils were obtained by functionalization of oligoalkylphenol.
