1189-93-1 Usage

Chemical Properties

clear colorless liquid

Uses

1,1,3,3,5,5-Hexamethyltrisiloxane is involved in the preparation of 2-bis(3-allyl-4-hydroxyphenyl)hexafluoropropane, which is associated with inorganic siloxane polymer and used as a coating material for the detection of toxic chemical warfare agents. It is also used as a silylating agent and to prepare 1,5-Bis[2-(1,2-epoxycyclohex-4-yl)ethyl]-1,1,3,3,5,5-hexamethyltrisiloxane from 4-vinyl-1-cyclohexene-1,2-epoxide by hydrosilylation.

Check Digit Verification of cas no

The CAS Registry Mumber 1189-93-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1189-93:
(6*1)+(5*1)+(4*8)+(3*9)+(2*9)+(1*3)=91
91 % 10 = 1
So 1189-93-1 is a valid CAS Registry Number.

Preparation of biomimetic membrane with hierarchical structure and honeycombed through-hole for enhanced oil–water separation performance

Luo, Shuai,Dai, Xueyan,Sui, Yanlong,Li, Peihong,Zhang, Chunling

, (2021)

Efficient oil–water separation plays a vital role in treating large amounts of industrial wastewater. However, current traditional separation methods are entwined with problems such as low efficiency and poor operability. Herein, we reported a nanofiber based on electrospinning and electrospray technology and spraying microspheres on the surface of a fiber mat for efficient oil–water separation. Owing to the electrostatic repulsion among the microspheres, the surface of the developed membrane had a honeycomb-like through-hole structure and super-high oil–water separation efficiency and oil flux. After 10 cycles, the membrane showed good separation efficiency and flux. This innovative work may provide a new idea and method for the design of biomimetic biopolymers, with broad application prospects in the field of oil–water separation.

Anionic and cationic ring-opening polymerization of 2,2,4,4,6,6-hexamethyl-8,8-divinylcyclotetrasiloxane

Teng, Conan J.,Weber, William P.,Cai, Guoping

, p. 5126 - 5130 (2003)

Ring-opening polymerization (ROP) of 2,2,4,4,6,6-hexamethyl-8,8-divinylcyclotetrasiloxane (I) initiated by both l-fert-butyl-4,4,4-tris(dimetnylamino)-2,2-bis[tris(dimethylamino)phosphoran-yli denamino]-2λ5,4λ5-catenadi(phosphazene) (C22H63N13P4, P4-t-Bu Superbase) and trifluoromethanesulfonic acid (CF3SO3H, triflic acid) has been studied. Both reactions lead to mixtures of linear copolymer, low molecular weight co-oligomers and monomeric cyclosiloxanes. The composition, molecular weight distribution, microstructure, and thermal properties of the copolymers have been determined. The copolymer microstructure has been determined by 29Si NMR spectroscopy. Monomeric cyclosiloxanes have been identified by GC/MS. Both copolymer microstructure and cyclosiloxanes formed depend on the particular catalyst system utilized. P4-t-Bu superbase-initiated anionic ROP of I leads to a copolymer with a random microstructure and to a series of monomeric cyclotetra-, cyclopenta-, and cyclohexasiloxanes formed by random combination of dimethylsiloxane (D) and divinylsiloxane (V) units. On the other hand, triflic acid-initiated ROP of I occurs in a chemoselective manner. This leads to a copolymer with a more ordered microstructure. In this case, I is the only monomeric cyclosiloxane found.

Hydrosilylation of Allyl Ethers in the Presence of Platinum(II) Immobilized on Polymethylene Sulfide

Effect of catalyst structure on the reaction of α-methylstyrene with 1,1,3,3-tetramethyldisiloxane

De Vekki,Skvortsov

body text, p. 762 - 777 (2009/09/26)

Reaction of α-methylstyrene with 1,1,3,3-tetramethyldisiloxane in the presence of the complexes of platinum(II), palladium(II) and rhodium(I) is explored. It is established that in the presence of platinum catalyst predominantly occurs hydrosilylation of α-methylstyrene leading to formation of β-adduct, on palladium catalysts proceeds reduction of α-methylstyrene, on rhodium catalysts both the processes take place. In the reaction mixture proceeds disproportion and dehydrocondensation of 1,1,3,3-tetramethyldisiloxane that leads to formation of long chain linear and cyclic siloxanes of general formula HMe2Si(OSiMe2) n H and (-OSiMe2-)m (n = 2-6, m = 3-7), respectively. Platinum catalysts promotes formation of linear siloxanes, while both rhodium and palladium catalysts afford linear and cyclic siloxanes as well. Structure of intermediate metallocomplexes is studied.
