    Physical Constants


    Parameter Value Remark
    Melting point -49 ℃ Liquid at all normal warehouse temperatures
    Boiling point 198–199 ℃ (760mmHg) High boiling point, low volatility

    Organic solubility Fully miscible with ethanol, methanol, acetone, ethyl acetate, toluene, xylene, chloroform, DMF; slightly soluble in aliphatic light oils

    Core Chemical Behaviors

    1. Active methylene \(-\mathbf{CH_2}-\) (key feature)

      The two adjacent carbonyl groups strongly withdraw electrons, making central hydrogens weakly acidic (pKa≈13). With weak base (sodium ethoxide, triethylamine), it forms enolate anion for alkylation, condensation and Michael addition — the classic Malonic Ester Synthesis core reaction.
    2. Alkylation reaction

      Reacts with alkyl halides (R-Cl / R-Br) to generate mono- and di-substituted malonate diesters. After alkaline hydrolysis and thermal decarboxylation, it produces substituted aliphatic carboxylic acids, widely used in drug fragment synthesis.
    3. Knoevenagel Condensation

      Condenses with aldehydes/ketones to form α,β-unsaturated diesters; raw material for coumarin fluorescent brighteners and heterocyclic drugs.
    4. Ester hydrolysis
    • Alkaline heating → disodium malonate; acidify to obtain malonic acid
    • Strong acid + high temp → decarboxylation, generates acetic acid derivatives
    1. Transesterification

      Exchanges ethoxy groups with other alcohols under acid/base catalyst to make dimethyl malonate, dibutyl malonate and other malonate esters.
    2. Thermal stability

      Stable below 180℃; above boiling point slowly decomposes, releasing ethanol and CO₂.
    3. Incompatible materials: Strong concentrated alkalis, strong oxidants, strong reducing agents.

    Reactive Group:

    Reactivity Alerts:

    Highly Flammable

    Reactivity Profile:

    Amines, such as FURFURYLAMINE, are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
