Equivalent to: Albemarle Ethanox 323;TACKIROL AP

Chemical Name: Nonylphenol Disulfide Oligomer

Specification:

Application:

Antioxidant 323 has double effect of both free radical termination and hydroperoxide decomposition. It means that it has the double functions of both the primary antioxodant and the secondary antioxidant.and it is also a kind of disulfide compunds.so it t act as vulcanization agent,anti-crystallization agent,antioxidant,catalysts in the manufacturing of light-colored rosin, disproportionated rosin, rosin resin, rosin esters,resins,adhesives,petroleum oil and waxes and deep processing.

 

characteristics

• The effects of antioxidation and color-fade of rosin and rosin resins (such as Glycerol ester of rosin, rosin pentaerythritol ester and malic acid resins) can be improved by adding antioxidant 323 with the amount of 0.2% to 0.3%, causing the color to improve with the subtractive effect achieving 2 to 3 units in the Gardner color scale.

• Disproportionation of rosin: antioxidant 323 is an efficient catalyst for the disproportionation of rosin. It converts instable conjugated double bond in the rosin molecule into stable conjugated double bond with an aromatic ring structure, which means to convert the abietic acid into dehydroabietic acid.
  The dosage of antioxidant 323 in the process is 0.1% to 0.3%, and optimum amount is 0.2%. Precious metals (such as platinum, palladium) used as disproportionation catalysts could be expensive. Antixodiant 323 is an ideal substitute with good quality and low costs.

• Anti-crystallization of rosin: Rosin is a non-crystalline transparent solid, but it tends to crystallize. Crystallization of rosin causes a reduction in rosin’s transparency and solubility, affecting its usage. Adding 0.2% antioxidant 323 to the rosin can improve its anti- crystallization performance.
