Safety Profile

Poison by ingestion, skin contact, and intraperitoneal routes. An experimental teratogen. An eye and skin irritant. When heated to decomposition it emits acrid smoke and fumes.

Purification Methods

Purify it by chromatography on neutral alumina and eluting with an ether/hexane mixture [see Izatt et al. Inorg Chem 14 3132 1975]. Dissolve it in ether at ca 40o, and spectroscopic grade MeCN is added to the solution, which is then chilled. The crown ether precipitates and is filtered off. It is dried in vacuo at room temperature [Wallace J Phys Chem 89 1357 1985]. [V.gtle ed. Top Corr Chem (Host Guest Complex Chemistry) 98 1981.] SKIN IRRITANT.

Check Digit Verification of cas no

The CAS Registry Mumber 16069-36-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,6 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16069-36:
(7*1)+(6*6)+(5*0)+(4*6)+(3*9)+(2*3)+(1*6)=106
106 % 10 = 6
So 16069-36-6 is a valid CAS Registry Number.

NMR spectra of guest-host complexes of boron and silicon fluorides with crown ethers in nonaqueous solutions

Gel'mbol'dt,Selig,Ganin,Fonar',Ennan

, p. 150 - 151 (2001)

19F, 11B, and 29Si NMR spectroscopy was used to examine the behavior of the guest-host complexes (BF3·H2O) 2·18-crown-6·2H2O, (BF3·H2O)2·DCH-6B,

Conductance study of binding of some Rb+ and Cs+ ions by macrocyclic polyethers in acetonitrile solution

Shamsipur, Mojtaba,Saeidi, Mahboubeh

, p. 1187 - 1198 (2007/10/03)

A conductance study of the interaction between Rb+ and Cs+ ions and 18-crown-6 (18C6), dicyclohexyl-18-crown-6 (DC18C6), dibenzo-18-crown-6 (DB18C6), dibenzo-24-crown-8 (DB24C8), and dibenzo-30-crown-10 (DB30C10) in acetonitrile solution has been carried out at various temperatures. The formation constants of the resulting 1:1 complexes were determined from the molar conductance-mole ratio data and found to vary in the order DC18C6 > 18C6 > DB30C10 > DB18C6 ~ DB24C8 for Rb+ ion and DC18C6 > 18C6 > DB30C10 ~ DB24C8 > DB18C6 for Cs+ ion. The enthalpy and entropy of complexation were determined from the temperature dependence of the formation constants. The complexes with the 18-crowns are both enthalpy and entropy stabilized while, in the case of large crown ethers, the corresponding complexes are enthalpy stabilized but entropy destabilized.
