Antioxidants, BHT, Butil Hydroxy Toluene

Products & Solutions

Antioxidants are used to protect materials against the negative influences of oxidation ie. discoloration, embrittlement and perishing in plastics and rubbers, gumming and polymerization in fuels and lubricants and loss of nutritional value (rancification) in fatty acids for both human and animal consumption.

 

How IONOL® Antioxidants Protect your Products from Oxidation
Antioxidants are sometimes called radical scavengers. They interrupt the self feeding chain of chemical reactions which characterize oxidation. A high level of protection can be achieved at relatively low concentrations if an IONOL® is used. The reaction firstly without and then with IONOL® antioxidant is detailed below:

Reaction without IONOL@ Antioxidants1. Chain Initiation

RH ->R. (free radical) + H.
RH + O2 ->R. (free radical) + HO2.

2. Chain Propagation
R. + O2 ->RO2. (peroxy radical)
RO2. + R'H ->ROOH (hydroperoxide) + R'. (free radical)

 

Reaction with IONOL@ Antioxidants

1. Chain Initiation
RH ->R. (free radical) + H.
RH + O2 ->R. (free radical) + HO2.

2. Chain Propagation
R. + O2 ->RO2. (peroxy radical)
RO2. + R'H ->ROOH (hydroperoxide) + R'. (free radical)

3. Chain Termination
RO2. + ArOH ->ROOH + ArO.

ArO. + R. ->ArOR
