英文回答：
Dimethylmethylphosphonate (DMMP) is a colorless, non-flammable, slightly viscous liquid with a boiling point of 193 °C. It is used as an intermediate in the production of organophosphorus compounds, such as pesticides and flame retardants. DMMP is also used as a solvent for a variety of organic and inorganic compounds.
The thermal decomposition of DMMP has been studied extensively. The decomposition products include dimethyl phosphite (DMP), methyl phosphate (MP), and phosphine (PH3). The relative amounts of these products depend on the temperature and the presence of a catalyst.
At temperatures below 200 °C, the decomposition of DMMP is slow and produces mainly DMP. As the temperature increases, the rate of decomposition increases and the amount of MP and PH3 produced also increases. In the
presence of a catalyst, such as a metal oxide, the decomposition of DMMP is accelerated and the yield of PH3
is increased.
The thermal decomposition of DMMP is a complex process that involves a number of different reaction pathways. The following is a simplified mechanism for the decomposition
of DMMP:
DMMP → DMP + CH3OH.
DMP → MP + CH3OH.
MP → PH3 + H3PO4。

The first step in the decomposition of DMMP is the formation of DMP. This reaction is followed by the
formation of MP and PH3. The overall reaction is exothermic and releases a large amount of heat.
The thermal decomposition of DMMP is a potential hazard. The decomposition products, such as PH3, are toxic and can
cause serious health problems. Therefore, it is important
to handle and store DMMP properly to avoid the risk of decomposition.

DMPA高温分解结构。

二甲基甲基膦酸酯（DMMP）是一种无色、不可燃、略粘稠的液体，沸点为193°C。

它用作制造有机磷化合物（如杀虫剂和阻燃剂）的中间体。

DMMP也用作多种有机和无机化合物的溶剂。

DMMP的热分解已被广泛研究。

分解产物包括二甲基亚磷酸酯(DMP)、甲基磷酸酯 (MP) 和膦 (PH3)。

这些产物的相对数量取决于
温度和催化剂的存在。

在低于200°C的温度下，DMMP的分解缓慢并主要产生DMP。

随
着温度升高，分解速度加快，MP和PH3的产生量也增加。

在催化剂（如金属氧化物）存在下，DMMP的分解会加速，PH3的产率也会增加。

DMMP的热分解是一个复杂的过程，涉及多种不同的反应途径。

以下是DMMP分解的简化机制：
DMMP → DMP + CH3OH.
DMP → MP + CH3OH.
MP → PH3 + H3PO4。

DMMP分解的第一步是形成DMP。

这个反应之后是MP和PH3的形成。

总体反应是放热的，释放出大量的热。

DMMP的热分解是一个潜在的危险。

分解产物，如PH3，是有毒的，可能导致严重的健康问题。

因此，妥善处理和储存DMMP以避免分解风险非常重要。
