Synthesis
5 parts of H-type ZSM-5 (SiO2 / Al2O3 = 280), 50 parts of diethylene glycol monomethyl ether, and diethylene glycol monoethyl ether 50 parts were charged into a reaction vessel and heated up to 180 ° C. under stirring for 8 hours It stirred. After cooling to room temperature, the reaction solution was measured the relative amounts of products were analyzed by gas chromatography. The composition of the resulting diethylene glycol ethyl methyl ether was 7.7%. Further, resulting in the product, diethylene glycol dimethyl ether and diethylene glycol diethyl ether, were contained in 3.7% and 5.2% of the composition ratio, respectively as by-products. By the diethylene glycol dimethyl ether exchange reaction together diethylene glycol monomethyl ether of the raw material, the diethylene glycol diethyl ether by ether exchange reaction together diethylene glycol monoethyl ether starting material, believed to be respectively obtained.
Check Digit Verification of cas no
The CAS Registry Mumber 1002-67-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1002-67:
(6*1)+(5*0)+(4*0)+(3*2)+(2*6)+(1*7)=31
31 % 10 = 1
So 1002-67-1 is a valid CAS Registry Number.

Decarbonylative ether dissection by iridium pincer complexes
Yoo, Changho,Dodge, Henry M.,Farquhar, Alexandra H.,Gardner, Kristen E.,Miller, Alexander J.M.
, p. 12130 - 12138 (2020/11/26)
A unique chain-rupturing transformation that converts an ether functionality into two hydrocarbyl units and carbon monoxide is reported, mediated by iridium(i) complexes supported by aminophenylphosphinite (NCOP) pincer ligands. The decarbonylation, which involves the cleavage of one C-C bond, one C-O bond, and two C-H bonds, along with formation of two new C-H bonds, was serendipitously discovered upon dehydrochlorination of an iridium(iii) complex containing an aza-18-crown-6 ether macrocycle. Intramolecular cleavage of macrocyclic and acyclic ethers was also found in analogous complexes featuring aza-15-crown-5 ether or bis(2-methoxyethyl)amino groups. Intermolecular decarbonylation of cyclic and linear ethers was observed when diethylaminophenylphosphinite iridium(i) dinitrogen or norbornene complexes were employed. Mechanistic studies reveal the nature of key intermediates along a pathway involving initial iridium(i)-mediated double C-H bond activation. This journal is
