Trioctyl phosphorotrithioite, also known as TOP, is a colorless to pale yellow liquid chemical compound with the formula (C8H17)3PS3. It is widely used as a catalyst in the production of polyurethane foams, silicone rubber, and other polymers. TOP is known for its ability to accelerate the reaction between isocyanates and polyols, which is crucial in the formation of polyurethane. It is also used as a flame retardant and a plasticizer. Due to its high reactivity and potential health risks, it is important to handle TOP with care, using appropriate safety measures.

1705-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1705-55-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1705-55:
(6*1)+(5*7)+(4*0)+(3*5)+(2*5)+(1*5)=71
71 % 10 = 1
So 1705-55-1 is a valid CAS Registry Number.

Syntheses und NMR-Spektren phosphororganischer Antioxidantien und verwandter Verbindungen

Koenig, T.,Habicher, W.D.,Haehner, U.,Pionteck, J.,Rueger, C.,Schwetlick, K.

, p. 333 - 349 (2007/10/02)

The syntheses of various aliphatic, aromatic, sterically hindered, and cyclic organophosphorus compounds (phosphorous acid esters, esters chlorides and ester amides, hydrogen phosphites, phosphinates and phosphates) are reported, and general procedures for preparation are given.The compounds synthesized were investigated by means of 31P-, 1H- and 13C-n.m.r. spectroscopy, and the chemical shifts measured are listed.

Organophosphorus Antioxidants. X. The Hydroperoxide Decomposing Action of Phosphites, Phosphonites and Thiophosphites

Koenig, T.,Habicher, W. D.,Schwetlick, K.

, p. 913 - 922 (2007/10/02)

The kinetics and mechanism of reactions of phosphites, phosphonites, thiophosphites and hydrogenphosphites with cumyl (CHP), t-butyl (TBHP) and α-tetralyl (THP) hydrogenperoxides has been studied by means of (31)P-n.m.r. spectroscopy, high performance liquid chromatography and iodometric titration.All three valent phosphorus compounds studied initially react with hydroperoxides stoichiometrically to give the corresponding P=O products and alcohol.Some species are able to decompose cumyl hydroperoxide catalytically to form phenol and aceton.Acyloin phosphites decompose CHP catalytically after a stoichiometric reaction as thiophosphites do.Tetramethylpiperidinyl phosphites ("HALS-phosphites") react with hydroperoxides only stoichiometrically but with high velocity.Phosphonites react with hydroperoxides in the same way as the corresponding phosphites.Their reactivity, however, is much higher.Hydrogenphosphites are less reactive than phosphites in the reaction with hydroperoxides.They are able to act catalytically.

Deodorized organothiophosphorous and emulsifiable concentrates thereof

-

, (2008/06/13)

Organothiophosphorous compounds, e.g., Merphos, which contain or develop malodorous mercaptan impurities during storage, are protected against such odor development by the addition of minor amounts (0.1 to 10%) of a ketone, especially in the presence of a catalyst such as cuprous chloride or p-toluene sulfonic acid in a concentration range of 0.01 to 0.1%. Formulated products are also claimed.
