26523-78-4 Usage
Chemical Properties
Light yellow transparent viscous liquid
Uses
Different sources of media describe the Uses of 26523-78-4 differently. You can refer to the following data:
1. Alkylphenols such as 4-nonylphenol (NP) and octylphenol (OP) can be generated by oxidation and subsequent hydrolysis of tris(nonylphenyl)phosphite (TNPP) used as additive in plastics. TNPP is used as a heat stabiliser in various polymeric food packaging materials such as styrenes, vinyl polymers, and rubber polyolefins. TNPP is also used to maintain the colour stability, processing stability, and performance integrity of the polymers. NP is used as a starting material in the manufacture of TNPP and so it may be present as an impurity as well as a hydrolysis product. Alkylphenols in food may also be occurred due to degradation of the most widely used non-ionic surfactants polyethoxylated nonylphenols (APEOs) which are cleaning agents in bottled manufacturing.
2. TNPP in combination with irganox is used to protect polyamide 6 (PA6) from oxidative degradation during the preparation of flame retardant nanocomposites. TNPP can be used as a stabilizer that prevents the molecular weight reduction and increases the tensile strength of the composite. It can also be used as a chain extender to improve the polymeric viscosity during the melt-blending of poly(hydroxybutyrate-co-hydroxyvalerate) based clay nanocomposites which find potential application as packaging materials.
General Description
Tris(nonylphenyl) phosphite (TNPP) is an antioxidant that is majorly used as a stabilizer to improve the performance of polyethylene by decomposing the hydroperoxides. It can also be used to enhance the thermal stability by extending the polymeric chains.
Check Digit Verification of cas no
The CAS Registry Mumber 26523-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,5,2 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26523-78:
(7*2)+(6*6)+(5*5)+(4*2)+(3*3)+(2*7)+(1*8)=114
114 % 10 = 4
So 26523-78-4 is a valid CAS Registry Number.
