Chemical Properties
Lead fluoborate is a nonflammable colorless
liquid or crystalline powder. Faint odor.
Uses
Different sources of media describe the Uses of 13814-96-5 differently. You can refer to the following data:
1. Used in tin-lead electroplatingLead(II) tetrafluoroborate is used as a catalyst involved in calixarene formation through hydrogen-bonded dimmers and in the preparation of linear polyesters. It is involved in the development and optimization of a bipolar lead-boron tetrafluoride accumulator. It is an electroplating solution for coating metal objects with lead and curing agent for epoxy resins. Further, it is used in printing lines, tin-lead alloy plating, lead soldering and also as a circuit board tin-lead alloy plating.
2. Catalyst for mediation of calixarene formation via hydrogen-bonded dimersAnalyzed in terms of electochemical characterization of the effects of impurities and organic additives in lead electrowinning from fluoroborate electrolyteUsed in the development and optimization of a bipolar lead-boron tetrafluoride accumulator
General Description
Odorless colorless liquid. An aqueous solution. Sinks and mixes with water.
Reactivity Profile
Solution is acidic and will corrode most metals [USCG, 1999]. Toxic and irritating hydrogen fluoride gas may form in fire [USCG, 1999].
Health Hazard
Early symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often of the ankles, is noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary tract; pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact with eyes or skin may cause burns and/or irritation.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride gas may form in fire.
Potential Exposure
This material is used in material finishing operations.

Check Digit Verification of cas no
The CAS Registry Mumber 13814-96-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,1 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13814-96:
(7*1)+(6*3)+(5*8)+(4*1)+(3*4)+(2*9)+(1*6)=105
105 % 10 = 5
So 13814-96-5 is a valid CAS Registry Number.

Electrochemical Generation of Soluble and Reactive Cadmium, Lead, and Thallium Cations in Noncoordinating Solvents: Relative Strengths of Perchlorate, Tetrafluoroborate, and Hexafluorophosphate Ligation in Dichloromethane and Benzene

Electrochemical oxidation of metal amalgam electrodes in noncoordinating solvents generates soluble forms of highly active metal ions at the electrode surface that can form very strong complexes with the tetrafluoroborate and perchlorate anions.Oxidation at Cd, Pb, and Tl dropping mercury amalgam electrodes in a solution containing dichloromethane and either tetrabutylammonium hexafluorophosphate, , tetrabutylammonium tetrafluoroborate, , or tetrabutylammonium perchlorate, , occurs reversibly, thereby allowing thermodynamic data to be obtained on the nature of the complex formed.The - ligation is considerably weaker than that of - or -.Data obtained in dichloromethane with hexafluorophosphate, as a reference electrolyte allowed the following complexes with their equilibrium constants to be identified: 2-, log β4=9.1; -, log β3=7.3; -, log β3=8.3; Pb(BF4)2, log β2=7.5; Tl(ClO4), log β1=3.3; Tl(BF4), log β1=2.9.The equilibrium constants for these complexes are larger then those obtained in aqueous media for many classical ligands.In benzene, which is of lower dielectric constant and is less polar than dichoromethane, the half-wave potential for the oxidation of the cadmium amalgam electrode is approximately 700 mV more negative with pechlorate than with hexafluorophosphate as the electrolyte anion.In contrast, the difference is only 200 mV in dichloromethane.This unprecendented difference may be attributed to the weaker coordination of benzene and the consequent amplification of the differences in strength of perchlorate and hexafluorophosphate ligation.Consequently, a method of preparing highly activated and previously unknown forms of soluble metal ions is available in solvents such as chlorinated and aromatic hydrocarbons. This feature is further illustrated by the large negative shift in half-wave potential for the metal oxidations observed after the coordinating solvent dimethyl sulfoxide is added to dichloromethane (0.2 M ) solutions.Controlled-potential electrolysis experiments at a mercury amalgam pool in dichloromethane lead to the formation of the expected nonsolvated insoluble salts, demonstrating that the kinetics of precipitation are slower then the polarographic time scale.Concepts developed on this work provide prospects for new forms of mechanistic, thermodynamic and synthetic metal ion chemistry.
