109888-72-4 Usage
General Description
1,3,5-Tris(2-methoxy-2-propyl)benzene is a complex organic compound known for its applications in the field of material science. Often presented as a clear, slightly yellow liquid, this benzene derivative consists of three long, branching alkyl chains attached to a central benzene ring, each ending in a methoxy group. These chemical features enable it to perform as a flexible, low-shrinkage crosslinker in multiple polymer systems, notably those used for encapsulation and sealants. Despite its utility, there appears to be limited information on its potential hazards or environmental effects, thus making careful handling and thorough safety assessments crucial.
Check Digit Verification of cas no
The CAS Registry Mumber 109888-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,8 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109888-72:
(8*1)+(7*0)+(6*9)+(5*8)+(4*8)+(3*8)+(2*7)+(1*2)=174
174 % 10 = 4
So 109888-72-4 is a valid CAS Registry Number.

METHOD FOR THE SYNTHESIS OF INITIATORS FOR TELECHELIC POLYISOBUTYLENES

Page/Page column 16, (2012/07/27)
A new methodology for the synthesis of a novel difunctional- and a known trifunctional initiator, i.e., 1,3-di(2-methoxy-2-propyl)-5-isopropyl benzene and 1,3,5-tri(2-methoxy-2-propyl) benzene, respectively, for the preparation of di- and tri-telechelic polyisobutylenes. The synthesis proceeds in three steps: 1) catalytic peroxidation of 1,3,5-triisopropylbenzene, 2) reduction of the peroxides to the corresponding alcohols, and 3) methylation of the alcohols. By controlling the conversion of the key peroxidation step the relative ratio of di- and tri-fiinctional intermediates can be controlled. By the use of the 1,3-di(2-methoxy-2-propyl)-5-isopropyl-benzene, well-defined di-methoxy telechelic polyisobutylenes can be synthesized. Although the overall combined yield of the two initiators was only 14-20%, because of the low cost of the starting material, reagents used, and simple manipulations these compounds represent the most cost effective initiators to-date for the preparation of telechelic polyisobutylenes.
