The content of C15H240 shall not be less than 98.5% calculated as anhydrous.
IONOL 75 is easily soluble in kerosene, oil and gasoline.
IONOL 75 conforms to the requirements of British Defense Standard 91/91, listed as RDE/A/609.
Also IONOL antioxidants have shown to increase the useful life of many industrial oils, reducing equipment downtime.
Applications include hydraulic fluids, transformer oils, spinning oils and metal rolling and cutting fluids.
IONOL antioxidants are excellent stabilizers for all grades of kerosene based Jet A1 fuel for civil and military use.
The concentration needed to protect and stabilize aviation fuels is also defined by these international specifications.
For example, DERD 2494 specifies an addition level in the range of 17.0 – 24.0 mg/L for hydrotreated fuels.
Uses of IONOL 75:
IONOL 75 is an oil-soluble antioxidant widely used at home and abroad.

Generally used in conjunction with BHA, and citric acid or other organic acids as a synergist.
China's provisions can be used for edible oil, fried food, biscuits, instant noodles, nuts canned, dry fish products, the maximum use of 0. 2g/kg.
IONOL 75 also has a certain antibacterial effect, but weaker than BHA.
Properties of IONOL 75:
IONOL 75 is colorless, white or off-white crystal or crystalline powder.
IONOL 75 is easily soluble in acetone, soluble in ethanol, insoluble in water and propylene glycol.

Absorption coefficient
Take IONOL 75, precision weighing, plus ethanol dissolution and quantitative dilution to make a solution containing about 50mg per lm l, according to UV-visible spectrophotometry (General Rule 0 @ 1), the absorbance was measured at a wavelength of 278nm, and the absorption coefficient (dish) was 80. 0 to 90. 0.
Nature of IONOL 75:
IONOL 75 is colorless crystal or white crystalline powder, odorless, tasteless.
Soluble in ethanol (25%,25 ° C), acetone (40%), benzene (40%), soybean oil, cottonseed oil, insoluble in water, glycerol, propylene glycol.
Light, thermal stability, heating can be volatilized with water vapor, the metal ion does not change color.
Preparation Method of IONOL 75:
p-cresol and tert-butyl alcohol are dissolved by heating, and phosphoric acid is used as catalyst to react at a certain temperature.
The reaction product is washed with sodium hydroxide solution to alkaline first, then washed with water to neutral, and finally distilled, recrystallization provides dibutyl hydroxytoluene.
Or isobutylene mixed with cresol and concentrated sulfuric acid, reaction at a certain temperature for a certain time, and the crude product is neutralized, and then the crude product is dissolved in ethanol, adding thiourea, hot filtration, spin drying, obtained by drying.
Differential Diagnosis of IONOL 75:
In the chromatogram recorded under the content determination item, the retention time of the main peak of the test solution should be consistent with the retention time of the main peak of the reference solution.
The infrared absorption spectrum of IONOL 75 should be consistent with that of the reference product (General rule 0402).
