二甲硫醚？

好像是有刺激性的硫化物，具體的不知道

復(fù)分解生成二甲硫醚和二甲基砜

Thermal and Chemical Stability of DMSO
DMSO is highly stable at temperatures below 150° C. For example, holding DMSO at 150° C for 24 hours, one
could expect a loss of between 0.1 and 1.0%. Retention times even in batch stills are usually considerably less than this, and
therefore, losses would be correspondingly less.. It has been reported that only 3.7% of volatile materials are produced during 72
hours at the boiling point (189° C) of DMSO (1). Slightly more decomposition, however, can be expected with the industrial grade
material. Thus, about 5% DMSO decomposes at reflux after 24 hours (3921). Almost half of the weight of the volatile materials is
paraformaldehyde. Dimethyl sulfide, dimethyl disulfide, bis(methylthio)methane and water are other volatile products. A small amount
of dimethyl sulfone can also be found. The following sequence of reactions explains the formation of these decomposition
products

我曾經(jīng)加錯藥品，把二氯亞砜與DMSO混合，結(jié)果就產(chǎn)生了刺激性的氣體，爆鳴聲。我也知道是怎么回事，估計和這個相似。

謝謝各位蟲蟲的幫助，我明白了！
