Description
Известно, что реакци этерификацик вл етс oonaDiMOji реакцией . Этим объ сн ет.- невозможность нолучени.ч 100% выходов сложных эфиров нри взаимодействии теоретически эквива. количеств спирта и органических кислот, так как состо н1 е равновес1 скоростей нроцесса этерифнкации и процесса расщеплени наступает примерно нри наличии 3 продукта этерификации.It is known that the esterification reaction is the oonaDiMOji reaction. This explains the impossibility of obtaining 100% of the yields of esters when interacting theoretically equivalent. quantities of alcohol and organic acids, since the equilibrium state of the esterification process and the cleavage process occurs approximately at the presence of 3 esterification products.
Описываемый сггособ получени слож1 ых зфнрс в HyTe.N) этерифнкации позвол ет проводить реакцию этерификации с выходом 90-98%. С этой целью органическую кислоту и кип т т в течение 1-2 часов в присутствии водного раствора серной кислгггы, пмеюидего коии .еит|;ацию около 40-50%.The described method of obtaining complex RNAs in HyTe.N) esterification allows the esterification reaction to be carried out in a yield of 90-98%. To this end, the organic acid is boiled for 1-2 hours in the presence of an aqueous solution of sulfuric acid, which contains about 40-50%.

Полученный сложный эфир имеет кисло1ное число 5-8 мг КОН, малоокраи,1еп выход гфодукта 90-98% от теоретически возможного.

The ester obtained has an acid number of 5–8 mg KOH, a low-cut, 1% yield of the product is 90–98% of theoretically possible. Re-esterification with the addition of 200 cm of water to the water layer yields an ana.; Logical results.
