10215-33-5 Usage
Description
Propylene glycol n-butyl ether (PnB) is an organic compound with a longer C4 alkyl carbon chain, which provides it with enhanced organic solvency compared to other ethers with shorter alkyl chains.
Uses
Used in the Paint and Coatings Industry:
Propylene glycol n-butyl ether is used as a coalescent solvent for improving latex film formation. The longer C4 alkyl carbon chain in PnB offers better organic solvency compared to the shorter methyl side chain group found in dipropylene glycol methyl ether (DPM). This makes PnB a more effective choice for coalescent solvents, as the complete water solubility of DPM limits the essential organic solubility required for good latex film formation.
Check Digit Verification of cas no
The CAS Registry Mumber 10215-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,1 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10215-33:
(7*1)+(6*0)+(5*2)+(4*1)+(3*5)+(2*3)+(1*3)=45
45 % 10 = 5
So 10215-33-5 is a valid CAS Registry Number.

Opening of Cyclic Acetals by Trichloro-, Dichloro- and Tribromo-borane
Bonner, Trevor G.,Lewis, David,Rutter, Keith
, p. 1807 - 1810 (2007/10/02)
The rate-determining step in the ring opening of cyclic acetals by trichloroborane to yield α-chloro-ethers is shown to be consistent with the formation of an oxocarbenium ion.Subsequent reduction provides a general route for the conversion of a diol into a hydroxy-ether.Tribromoborane is a more powerful and dichloroborane a less powerful reagent than trichloroborane.
