- A liquid organic tin antimony compound and its preparation method and application (by machine translation)
-
The invention relates to a liquid organic tin antimony compound and its preparation method, compounds of tin and antimony in the total content is more than 18%, its preparation method is as follows: (1) will be mercapto acetic acid, catalyst and dihydric alcohol mixing, stirring, heating to 70 - 120 °C, vacuum degree is - 0.06 - - 0.09 mpa conducted under the conditions of the reaction, the reaction to the water separator was no longer in the water to trickle out, cooling to room temperature, water washing, takes the oil phase, distillation and dehydration under reduced pressure, to obtain the mercapto compound; (2) step (1) made of a mercapto compound, isooctyl thioglycolate, methyl chloride and water mixing, heating up to 40 - 80 °C, into the antimony trioxide, adding inorganic alkali to adjust the pH value is 6 - 8, then the stirring reaction 4 - 6 hours, after the reaction takes the oil phase, dewatering filtering, to obtain the liquid organic tin antimony compound. The invention organic tin antimony compound metal content is high, low toxicity and environmental protection, is suitable for various types of hard PVC material, has an excellent initial and long-term thermal stability, product high transparency.

- Synthesis of 12- and 13-membered sulfur-containing lactones by homolytic macrocyclization of mercaptoacetic esters with alkynes
-
Starting from mercaptoacetic acid esters of 1,2- or 1,3-diols and substituted acetylenes 12- and 13-membered sulfur-containing lactones as 1:1 adducts were synthesised in yields up to 48%. The mechanism of this homolytic reaction, which is initiated by the tripropylborane/oxygen system, includes generation of thiyl radicals and their addition to the triple bond of alkynes.
