Explosion Limits of Flammable Gases.
Netsu Bussei, 1994 可燃性気体が空気や酸素と混合した系に、 熱や火花などによりエネルギーが与えられると爆発反応を起こすことはよく知られているが、 可燃性気体の種類により爆発を起こす濃度範囲や爆発を起こすのに必要なエネルギー値に違いのあることはあまり知られていない。 本解説では、 爆発反応が起こる限界濃度に着目し、 その理論的取扱いや測定方法および圧力・温度などの外部因子がこの限界濃度に与える影響について概説したものである。

Advanced Functional Materials, EarlyView.Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Explosion Limits of Butadiene Mixed with Air
Nippon kagaku zassi, 1966 従来の研究に引きつづき,プタジエン-空気系の爆発限界を注入法で決定した。爆発反応は,普通爆発と二段爆発であり,誘導期間は通常数秒以内であるが,爆発半島内では2～3分におよぶものもあった。等圧,等温爆発限界曲線はU字型を示す。等組成曲線で,ブタジエン組成20%のものが一番爆発しやすいことがわかり,またブタジエン組成2～3%,圧力25cmHg以下において爆発半島が存在することがわかった。この爆発反応が熱爆発であるとすると反応次数は2次となり,見かけの活性化エネルギーは約33kcal/molであるが,ブタジエン濃度の増加につれて減少している。生成物や爆発の様相から判断して,ブタジエン-空気系の爆発反応においては,ブタジエン濃度の低い組成の混含ガスでは酸化反応が ...
