Abstract

Спосіб отримання метилових ефірів з кукурудзяної олії включає процеси фільтрації з відділенням супутніх домішок, нейтралізації вільних жирних кислот, промивання олії сольовим розчином і водою, очищення від домішок та переестерифікацію. Використовують кукурудзяну олію із вмістом вільних жирних кислот 5-20 мг КОН/г, а їх нейтралізацію здійснюють проведенням реакції естерифікації концентрованою сірчаною кислотою - 1,5 % до маси, протягом 2 год. за температури 60-65 °С при постійному перемішуванні з відділенням води і спирту. Метанол і сірчану кислоту беруть у молярному співвідношенні 6:1 та направляють на переестерифікацію з додаванням метанолу і каталізатора - КОН.The method of obtaining methyl esters from corn oil involves filtration processes with the separation of associated impurities, neutralization of free fatty acids, washing the oil with saline and water, impurity removal and transesterification. Use corn oil with a content of free fatty acids 5-20 mg KOH / g, and their neutralization is carried out by esterification with concentrated sulfuric acid - 1.5% by weight, for 2 hours. at a temperature of 60-65 ° C with constant stirring with the separation of water and alcohol. Methanol and sulfuric acid are taken in a molar ratio of 6: 1 and sent for transesterification with the addition of methanol and a KOH catalyst.
