15773-53-2 Usage

Uses

Used in Automotive Industry:
Lead dihexanoate is used as a lubricant additive for its exceptional thermal stability and lubricating properties, particularly in the formulation of lubricating greases. It is especially suitable for high-temperature applications such as automotive engines, where its performance is critical for the smooth operation of mechanical components.
However, it is important to note that due to the significant health risks associated with lead dihexanoate, including its high toxicity and potential to cause neurological disorders, reproductive issues, and organ damage, its use in consumer products has been heavily restricted in many countries. This is to ensure the safety of both individuals and the environment, highlighting the need for alternative, less harmful lubricant additives in various applications.

Check Digit Verification of cas no

The CAS Registry Mumber 15773-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,7 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15773-53:
(7*1)+(6*5)+(5*7)+(4*7)+(3*3)+(2*5)+(1*3)=122
122 % 10 = 2
So 15773-53-2 is a valid CAS Registry Number.

Coordination geometry of lead carboxylates - Spectroscopic and crystallographic evidence

Catalano, Jaclyn,Murphy, Anna,Yao, Yao,Yap, Glenn P. A.,Zumbulyadis, Nicholas,Centeno, Silvia A.,Dybowski, Cecil

, p. 2340 - 2347 (2015/01/30)

Despite their versatility, only a few single-crystal X-ray structures of lead carboxylates exist, due to difficulties with solubility. In particular, the structures of long-chain metal carboxylates have not been reported. The lone electron pair in Pb(ii) can be stereochemically active or inactive, leading to two types of coordination geometries commonly referred to as hemidirected and holodirected structures, respectively. We report 13C and 207Pb solid-state NMR and infrared spectra for a series of lead carboxylates, ranging from lead hexanoate (C6) to lead hexadecanoate (C18). The lead carboxylates based on consistent NMR parameters can be divided in two groups, shorter-chain (C6, C7, and C8) and longer-chain (C9, C10, C11, C12, C14, C16, and C18) carboxylates. This dichotomy suggests two modes of packing in these solids, one for the short-chain lead carboxylates and one for long-chain lead carboxylates. The consistency of the 13C and 207Pb NMR parameters, as well as the IR data, in each group suggests that each motif represents a structure characteristic of each subgroup. We also report the single-crystal X-ray diffraction structure of lead nonanoate (C9), the first single-crystal structure to have been reported for the longer-chain subgroup. Taken together the evidence suggests that the coordination geometry of C6-C8 lead carboxylates is hemidirected, and that of C9-C14, C16 and C18 lead carboxylates is holodirected.

Study of the solubilities of zinc and lead caproates in n-decane

Perov,Il'ina,Irkhina,Goncharova

, p. 700 - 701 (2008/10/08)

The solubilities of zinc and lead caproates in n-decane, a nonpolar aliphatic hydrocarbon, is studied by the immersion filtration method at temperatures of 25, 50, 75, 100, 150, and 174°C. The heats of melting and the melting points of thermally unstable carboxylates estimated by the Schroeder equation are found to be 4.9 kJ/mol and 440°C for Zn(n-C5H11COO)2 and 4.8 kJ/mol and 380°C for Pb(n-C5H11COO)2, respectively.
