我将从以下五个方面为你介绍 “diol” 这个单词：
1. 定义：
“diol” 是指分子中有两个羟基 (-OH) 的有机化合物。它也可以是分子中有两个羟基官能团的单元。
2. 化学性质：
Diol 包含两个羟基官能团，因此它具有吸水性、亲水性和缩合性。 Diol 也可以被氧化为二酮。
3. 应用：
Diol 作为有机合成反应的重要原料，广泛用于医药、染料、涂料等行业。
4. 常见的 diol：
Ethylene glycol, propylene glycol, butanediol, pentanediol, hexanediol, etc.
5. 示例句子：
1. This plastic is made by reacting diols with diisocyanates.
这种塑料是通过将二元醇与二异氰酸酯反应制成的。
2. Polyurethanes are formed by reacting diisocyanates with diols.
聚氨酯是由二异氰酸酯与二元醇反应形成的。
3. This biological system involves the cleae of diols.
这个生物系统涉及到二元醇的裂解。
4. The team discovered a new method for synthesizing diols in the laboratory.
该团队发现了一种在实验室中合成二元醇的新方法。
5. The diol compound is commonly used as a plasticizer in coatings and adhesives.
二元醇化合物通常作为涂料和胶黏剂中的增塑剂使用。
diol的中文翻译为二醇，读音为 /ˈdaɪəl/。
例句：
1. Ethylene glycol is a diol commonly used as antifreeze.
乙二醇是一种常用的防冻剂二醇。
2. The structure of a diol molecule contains two hydroxyl (-OH) groups.
二醇分子的结构含有两个羟基(-OH)官能团。
3. Diols can be used as solvents, plasticizers, and raw materials for the production of polyesters.
二醇可以用作溶剂、增塑剂，并且也是制备聚酯的原材料。
diol在中文中有”辛二醇、二醇基”的意思，在英美地区还有”化”的意思，发音音标为[‘daiәul]，diol在英语中经常以名词形式出现，在《瓦里希英汉词典》中，共找到44个与diol相关的句子。
1.辛二醇
例句:The process comprises dehydrating a diol in the presence of a catalyst comprising cerium oxide supported on a carrier. (该方法包含在催化剂的存在下使二醇脱水，该催化剂包含负载于载体上的氧化铈。)
2.二醇基
例句:Vicinal diol can be effectively translated into azelaic acid and the corresponding dicarboxylic acid monomethyl ester. (邻二醇可以有效地转化为壬酸和相应的二元酸单甲酯。)
3.化
例句:METHODS The title compound was synthesized from 2-butene-1,4-diol, via esterification, epoxidation, amination, then amidation with tetraiodoterebenzoyl chloride. (方法以1，4-丁烯二醇为原料，经过酯化、环氧化、氨解开环，再与四碘对苯二甲酰氯反应合成目标产物。)
4.孕淄烷二醇、化
例句:The synthesis of oxyethylene oxypropylene copolyethers used for quenchant was studied by using anionic ring opening polymerization, diol or triol as the starting agent and KOH as the catalyst. (翻译:研究了以KOH为催化剂，二元或三元醇为起始剂，采用阴离子开环聚合合成淬火剂用共聚醚。结果表明：产物的分子量随起始剂和杂质量的减少而增加； )
diol一般作为名词使用，如在diol phase(二醇基相)、diol salt(二醇盐)、estrane diol(雌甾烷二醇)等常见短语中出现较多。
1. METHODS The title compound was synthesized from 2-butene-1,4-diol, via esterification, epoxidation, amination, then amidation with tetraiodoterebenzoyl chloride. (翻译:方法以1，4-丁烯二醇为原料，经过酯化、环氧化、氨解开环，再与四碘对苯二甲酰氯反应合成目标产物。)
2. The synthesis of oxyethylene oxypropylene copolyethers used for quenchant was studied by using anionic ring opening polymerization, diol or triol as the starting agent and KOH as the catalyst. (翻译:研究了以KOH为催化剂，二元或三元醇为起始剂，采用阴离子开环聚合合成淬火剂用共聚醚。结果表明：产物的分子量随起始剂和杂质量的减少而增加； )
3. In the experiment, di-isocyanate, polyether diol and a hydrophilic chain-extender were used to synthesize aqueous urethane. (翻译:实验采用二异氰酸酯与聚醚二元醇、亲水扩链剂反应合成水性聚氨酯。)
4. The effects of diol content on the dynamic mechanical properties and impact strength of the blends were investigated. (翻译:系统地研究了二元醇含量对共混材料动态力学性能、冲击性能的关系。)
5. 4 diol . com also reserves the right to change the layout , color , size and font of any articles posted. (翻译:4译友在线同时保留删除论坛帖子，以及修改用户所张贴文章格式、字体、文字大小、颜色等的权利。)
6. wherein the solvent in the microemulsion is a vicinal diol such as 1, 2-hexanediol. (翻译:其中微乳液中的溶剂是连位二醇如1,2-己二醇。)
diol作为名词的时候，其近义词以及反义词有s、diols等。
