实验性质
| 外观 / 形态 : | Fumaric acid appears as a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Combustible, though may be difficult to ignite. Used to make paints and plastics, in food processing and preservation, and for other uses.；Liquid; Other Solid; Dry Powder; CBI; Large Crystals；White crystalline powder or granules；Colorless or white odorless solid; [HSDB] White crystalline solid; [MSDSonline]；Solid；ODOURLESS COLOURLESS CRYSTALLINE POWDER.；white odourless granules or leafy crystals; virtually odourless with tart acid taste |
