  Improved Protocol Toward 1,3,4-Oxadiazole-2(3H)-thiones and Scale-up Synthesis in the Presence of SDS as a Micelle Promoted Catalyst

  摘要：

  Convenient procedure for in situ cyclization of hydrazinecarbodithioate potassium salts to 1,3,4-oxadiazole-2(3H)-thiones under normal phase micellar media catalysis promoted by sodium dodecyl sulfate (SDS) as an anionic surfactant is reported. The main advantage of this procedure is to provide shorter reaction time for the completion of cyclization; scale-up synthesis is possible and the oxadiazoles were obtained in high to excellent yields (87-100%), making the protocol an attractive alternative to the available methods.

  The object of the present invention is to provide a reversible heat sensitive recording material capable of formation and erasion of images with a clear contrast and capable of retaining stable images with time under the conditions of daily living. A reversible heat sensitive recording material comprising a support and, provided thereon, a normally colorless or light colored dye precursor and a reversible color developer which causes reversible change of color tone in the dye precursor due to the difference in cooling rate after heating, characterized in that said reversible heat sensitive recording material contains at least one specific color erasion accelerator containing a long chain alkyl group. Furthermore, a reversible heat sensitive recording material in which the recorded images can be erased by simple methods, such as leaving it in natural environment or at relatively low temperatures or heating it by a drier, characterized in that a specific compound having a long chain alkyl group and an imide group as the reversible color developer and a specific amine compound having a long chain alkyl group or an imide-containing compound as the color erasion accelerator are used in combination.

  本发明的目的是提供一种可逆的热敏记录材料，能够形成和擦除具有清晰对比度的图像，并能在日常使用条件下保持稳定的图像。该可逆的热敏记录材料包括支撑体和通常为无色或浅色的染料前体以及可逆的色彩发展剂，由于加热后冷却速率的差异，导致染料前体的色调可逆变化，其特征在于该可逆的热敏记录材料含有至少一种具有长链烷基的特定颜色消除加速剂。此外，本发明还提供了一种可逆的热敏记录材料，其中记录的图像可以通过简单的方法擦除，例如将其放置在自然环境中或在相对较低的温度下或通过烘干机加热，其特征在于使用具有长链烷基和酰亚胺基的特定化合物作为可逆的色彩发展剂，并使用具有长链烷基或含酰亚胺的化合物作为颜色消除加速剂。

  A polyacetal resin composition comprises a polyacetal resin, and at least one carboxylic acid hydrazide selected from a saturated or unsaturated long-chain aliphatic carboxylic acid hydrazide, a saturated or unsaturated alicyclic carboxylic acid hydrazide, a dimer acid or trimer acid hydrazide, and an oxycarboxylic acid hydrazide corresponding to each of these hydrazides. The proportion of the carboxylic acid hydrazide may be about 0.001 to 20 parts by weight relative to 100 parts by weight of the polyacetal resin. The polyacetal resin composition may further comprise at least one member selected from an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, an impact resistance improver, a slip-improving agent, a coloring agent, and a filler. With the use of such a resin composition, stability of a polyacetal resin is improved, and formaldehyde emission is inhibited.
