3050-88-2 Usage
General Description
TRIS(NONYLPHENYL) PHOSPHITE, also known as TNPP, is a phosphite antioxidant commonly used in the production of plastics, rubber, and other polymers. It acts as a stabilizer and thermal decomposer, helping to prevent the degradation of materials during processing and use. TNPP is known for its ability to protect materials from heat and oxygen-induced degradation, and is often used in combination with other antioxidants to provide a synergistic effect. It is a viscous, pale yellow liquid that is soluble in organic solvents, making it easy to incorporate into various formulations. TNPP is considered to be relatively safe for use, but it is important to handle and store it properly to minimize any potential hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 3050-88-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3050-88:
(6*3)+(5*0)+(4*5)+(3*0)+(2*8)+(1*8)=62
62 % 10 = 2
So 3050-88-2 is a valid CAS Registry Number.

-
Paragraph 0012; 0013; 0014, (2016/11/14)
The invention discloses a synthesis method of trinonylphenol phosphite ester. The method specifically comprises the following steps of firstly mixing triphenyl phosphite and photoinitiator and introducing nitrogen for replacement, and then reducing pressure, heating up to 120 DEG C and dehydrating for 30min; secondly controlling the pressure of the reaction system at 0.1 to 0.6MPa at 130 to 180 DEG C, and irradiating the reaction system for 1h under an ultraviolet light source with wavelength at 315 to 400nm; lastly cooling and reducing the pressure to remove nonylene which is not reacted, and lowering the temperature to 40 to 50 DEG C continuously so as to obtain the trinonylphenol phosphite ester. By using ultraviolet light catalytic reaction, the synthesis method disclosed by the invention is mild in conditions, easy to control, safe and convenient to operate, friendly to human, equipment and environment, and high in feedstock conversion and product yield; three wastes and by-products are not produced; and the quality indicators of the products are excellent.
