Novel organosiloxane compounds are disclosed that are useful in firefighting foams. Methods of making and using the organosiloxane compounds and foams are also described.
There is provided a process for preparing β-mercaptocarboxylic acid represented by the following General Formula (3) comprising step of reacting hydrogen sulfide, alkali hydroxide represented by a formula: XOH (X represents Na or K), and unsaturated carboxylic acid represented by the following General Formula (1) under atmospheric pressure to obtain a reaction solution including a compound represented by the following General Formula (2) and step of neutralizing the reaction solution in an acid. An amount of the alkali hydroxide is equal to or greater than total moles of the unsaturated carboxylic acid and the hydrogen sulfide.

A series of hydrophilic per‐6‐thio‐6‐deoxy‐γ‐cyclodextrins (CDs) were synthesized from per‐6‐iodo‐6‐deoxy‐γ‐CD. These new hosts are able to solubilizepolycyclicaromatic guests in aqueous solution to much higher extents than native CDs. Phase‐solubility diagrams were mostly linear in accordance with both 1:1 and 1:2 CD–guest complexes in aqueous solution. The stoichiometry of the inclusion complexes

crystallographic determination and spectroscopic characterization of gadolinium(III), terbium(III) and europium(III) 3-mercaptopropionate complexes, aqua-tris(3-mercaptopropionate)lanthanide(III) - [Ln(mpa)3(H2O)]. The Judd-Ofelt intensity parameters were experimentally determined from emission spectrum of the [Eu(mpa)3(H2O)]complex and they were also calculated from crystallographic data. The complexes are coordination
