84-77-5 Usage
Description
Didecyl phthalate is a synthetic organic compound primarily used as a plasticizer for various polymers, enhancing their flexibility and workability. It is a colorless, odorless liquid with a high molecular weight, and it is soluble in organic solvents but not in water. Its chemical structure consists of two didecyl chains connected by a phthalate group, which allows it to interact with polymer chains and increase their mobility.
Uses
Used in Plastics and Polymer Industry:
Didecyl phthalate is used as a primary plasticizer for vinyl resins, such as polyvinyl chloride (PVC), to improve their flexibility, workability, and processability. It helps to reduce the brittleness and stiffness of the polymer, making it more suitable for various applications.
Didecyl phthalate is also used as a plasticizer for polystyrene, a common thermoplastic polymer used in the production of disposable cutlery, CD cases, and other consumer products. Its compatibility with polystyrene allows for the creation of flexible and durable materials with improved mechanical properties.
Additionally, didecyl phthalate is used in cellulosics, which are natural polymers derived from cellulose, a complex carbohydrate found in plant cell walls. Cellulosics are used in various applications, such as textiles, paper products, and films. The use of didecyl phthalate as a plasticizer in cellulosics helps to enhance their flexibility, durability, and overall performance.
Preparation
Didecyl phthalate is synthesized by esterification of phthalic anhydride and decyl alcohol. The production methods of phthalate plasticizers are common, see the production method of dioctyl phthalate (C24H38O4, [117-84-0]. In actual industrial products, there is no complete linear Didecyl phthalate is a mixture of branched chain esters, but the ratio of isomers is different.
Check Digit Verification of cas no
The CAS Registry Mumber 84-77-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84-77:
(4*8)+(3*4)+(2*7)+(1*7)=65
65 % 10 = 5
So 84-77-5 is a valid CAS Registry Number.
