Description
Octadecanedioic acid, also known as sebacic acid, is an alpha, omega-dicarboxylic acid derived from octadecane, in which both terminal methyl groups are replaced by carboxy groups. It is a fine particle pollutant emission resulting from the fireplace combustion of woods grown in Southern USA.
Uses
Used in Chemical Industry:
Octadecanedioic acid is used as a chemical intermediate for the production of various chemicals, including nylon, alkyd resins, and plasticizers. Its unique structure allows it to form strong polymers and contribute to the durability and flexibility of the end products.
Used in Environmental Applications:
As a fine particle pollutant, Octadecanedioic acid plays a role in air quality and pollution control. Efforts to reduce its emissions can contribute to improved air quality and human health, particularly in regions where wood combustion is a common practice.
Used in Biodegradable Polymers:
Octadecanedioic acid is used as a monomer in the synthesis of biodegradable polymers, such as polybutylene succinate (PBS) and polybutylene adipate terephthalate (PBAT). These polymers have potential applications in packaging, agriculture, and other industries, offering a more sustainable alternative to traditional petroleum-based plastics.
Used in Lubricants and Additives:
Due to its dicarboxylic acid structure, Octadecanedioic acid is used in the formulation of lubricants and additives for various industrial applications. It can improve the performance and longevity of machinery and equipment by reducing friction and wear.
Used in Cosmetics and Personal Care:
Octadecanedioic acid is used as a component in cosmetics and personal care products, such as creams, lotions, and shampoos. Its emulsifying and thickening properties contribute to the stability and texture of these formulations, enhancing their performance and user experience.
Check Digit Verification of cas no
The CAS Registry Mumber 871-70-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 871-70:
(5*8)+(4*7)+(3*1)+(2*7)+(1*0)=85
85 % 10 = 5
So 871-70-5 is a valid CAS Registry Number.
