N,N'-hexanediyl-bis-carbamic acid dicyclohexyl ester, also known as hexamethylene bis-urea dicyclohexyl ester, is a chemical compound with the molecular formula C20H36N2O4. It is a white crystalline solid that is soluble in most organic solvents. N,N'-hexanediyl-bis-carbamic acid dicyclohexyl ester is primarily used as a plasticizer for various polymers, such as PVC, due to its ability to increase flexibility and durability. It is also known for its low volatility and resistance to extraction, making it suitable for applications where long-term stability is required. The compound is synthesized by reacting hexamethylene diisocyanate with dicyclohexylamine, followed by a reaction with alcohol to form the ester. It is important to handle this chemical with care, as it may have potential health and environmental impacts, and appropriate safety measures should be taken during its use and disposal.

3066-64-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3066-64-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,6 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3066-64:
(6*3)+(5*0)+(4*6)+(3*6)+(2*6)+(1*4)=76
76 % 10 = 6
So 3066-64-6 is a valid CAS Registry Number.

Method for Preparing Dicarbamate Compounds

-

Paragraph 0032-0033; 0056-0057; 0067-0070, (2017/01/02)

The present invention provides a preparing method of dicarbamate, comprising: a first step of obtaining an alcohol solution including diureido obtained by reacting diamine having 2 to 13 carbon atoms with urea in the presence of alcohol having 3 to 12 carbon atoms at low temperature of 150anddeg;C or less; and a second step of obtaining dicarbamate by reacting the alcohol solution including the diureido at high temperature of 200anddeg;C or more under carbon dioxide pressure. According to the preparing method of the present invention, yield and selectivity of dicarbamate are significantly increased, and formation of an alkylated amine by-product can be minimized.COPYRIGHT KIPO 2016
