Otgoi Yuihaks from LTPAR / ATA mix. This product is made of nzopropyl acid, isonrop benzoate, benzoic acid and soda. condepsir c1 is separated in two layers: the lower iodine-syrt layer is ve-chyero-ether-alcohol. The layer, which constitutes 5–18% of the total condensate, has a 33% easily strengthened isopropyl alcohol. Isopropyl alcohol is first distilled off from the upper layer, then treated with soda ash to wash out the benzoic acid, which is then washed.
