Positive reactions were observed to 2-hydroxyethyl methacrylate (2- HEMA), 2-hydroxypropyl methacrylate (2- HPMA) and ethyleneglycol dimethacrylate (EGDMA). Subsequent analysis showed that the electrode hydrogel contained acrylic acid as an impurity.

Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group. The naming of these compounds is governed by IUPAC nomenclature, which ensures systematic and consistent naming of chemicals. Numerous organic compounds have other common names, often originating in historical source material thereof.

羧基的 化學式 為-C (=O)OH，通常寫成-COOH或-CO 2 H，它是由一個 羰 tāng 基 [1] （>C=O）和一個 羥 qiǎng 基 [4] （-O-H）組成的複合 官能基。 羧酸是 質子 （H +）授予者，也就是 質子酸 （布-洛酸）。 可分為 脂肪酸 及 芳香酸 二大類。 螞蟻 和 蜜蜂 的分泌液中含的 甲酸 H-COOH、使 醋 有 酸味 的 乙酸 CH 3 -COOH...等都是常見的羧酸。 擁有兩個羧基的分子叫二酸，最簡單的分子是由兩個羧基結合而成的 草酸 (COOH) 2。 其他像是可在 檸檬 中發現的 檸檬 …

In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C (=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO2H, sometimes as R−C (O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups.

二羧酸是指含有两个 羧基 官能团 的有机化合物，分子通式常写为HOOC-R-COOH。 可以使用二羧酸来制备 共聚物，比如 聚酰胺 、 聚酯 等 [1]。

羧酸 [2]（RCOOH）（Carboxylic Acid）是最重要的一类 有机酸。 一类 通式 为RCOOH或R (COOH)n 的化合物， 官能团：－COOH。 X射线衍射证明，甲酸中羰基的键长123pm长于正常的羰基122pm;C－O的键长131pm小于醇中的 C－O的键长143pm；在甲酸晶体中，两个碳氧键键长 …

Example: calculating molar mass Let's calculate the molar mass of carbon dioxide (CO 2): Carbon (C) has an atomic mass of about 12.01 amu. Oxygen (O) has an atomic mass of about 16.00 …
