產(chǎn)品詳情

詳細(xì)信息(中文)：
物理性質(zhì)
相對蒸氣密度（空氣=1）：3.66
飽和蒸氣壓(kPa)：0.13(26℃)
折射率：1.5455
引燃溫度(℃)：192
醛基上的碳氧雙鍵會與苯環(huán)上的大π鍵共軛，共有8個π電子
溶解性：微溶于水，約為0.6wt（20°C）可混溶于乙醇、乙醚、苯、氯仿。
化學(xué)性質(zhì)
苯甲醛的化學(xué)性質(zhì)與脂肪醛類似，但也有不同。苯甲醛不能還原費林試劑；用還原脂肪醛時所用的試劑還原苯甲醛時，除主要產(chǎn)物苯甲醇外，還產(chǎn)生一些四取代鄰二醇類化合物和均二苯基乙二醇。在氰化鉀存在下，兩分子苯甲醛通過授受氫原子生成安息香。苯甲醛還可進(jìn)行芳核上的親電取代反應(yīng)，主要生成間位取代產(chǎn)物，例如硝化時主要產(chǎn)物為間硝基苯甲醛。 [2] 空氣中極易被氧化，生成白色苯甲酸。可與酰胺類物質(zhì)反應(yīng)，生產(chǎn)醫(yī)藥中間體。
用途.
【用途一】重要的化工原料，用于制月桂醛、月桂酸、苯乙醛和苯甲酸芐酯等，也用作香料
【用途二】用作測定臭氧、酚、生物堿和位于羧基旁的亞甲基試劑
【用途三】可作為特殊的頭香香料，微量用于花香配方，如紫丁香、白蘭、茉莉、紫羅蘭、金合歡、葵花、甜豆花、梅花、橙花等中。香皂中亦可用之。還可作為食用香料用于杏仁、漿果、奶油、櫻桃、椰子、杏子、桃子、大胡桃、大李子、香莢蘭豆、辛香等香精中。酒用香精如朗姆、白蘭地等型中也用之
【用途四】苯甲醛是除草劑野燕枯、植物生長調(diào)節(jié)劑抗倒胺的中間體
【用途五】GB 2760--1996規(guī)定為暫時允許使用的食用香料。主要用于配制杏仁、櫻桃、桃子、果仁等型香精，用量可達(dá)40%。作為糖水櫻桃罐頭的賦香劑，加入量每kg糖水3ml
【用途六】醫(yī)藥、染料、香料的中間體。用于生產(chǎn)間氧基苯甲醛、月桂酸、月桂醛、品綠、苯甲酸芐酯、芐叉苯胺、芐叉丙酮等。用以調(diào)合皂用香精、食用香精等
【用途七】有機(jī)合成, 溶劑, 測定臭氧及位于羰基旁邊的亞甲基，檢定酚和生物堿，香料制備 [5]

Saturated vapor pressure (kPa) : 0.13 (26 ℃)
The refractive index: 1.5455
Ignition temperature (℃) : 192
Aldehyde group on the double bond of carbon oxygen with large PI conjugate benzene rings, a total of eight PI electrons
Solubility: slightly soluble in water, which is about 0.6 wt (20 ° C) can be soluble in ethanol, ethyl ether, benzene, chloroform.
Chemical properties
Chemical properties of benzaldehyde like fatty aldehyde, but there are also different. Benzaldehyde can't restore fehling reagent; With reduction of fatty aldehyde reagents used in the reduction of benzene, formaldehyde, in addition to the main products of benzyl alcohol, also produce some four instead of neighbouring diol compounds and diphenyl ethylene glycol. In the presence of cyanide, two molecules of benzaldehyde by giving generate benzoin hydrogen atoms. Benzaldehyde can also be of aromatic electrophilic substitution reaction on nuclear, mainly generated between a substitution product, such as main product for nitrobenzene formaldehyde between nitrification. [2] easily oxidized in the air, produce white benzoic acid. Can react with amide class material, the production of pharmaceutical intermediates.
Purposes.
Important chemical raw material, USES a 】【 for making lauric aldehyde, lauric acid, benzene acetaldehyde and benzyl benzoate etc, also used as a spice
Used for determination of ozone, phenol, use 2 】【 alkaloids and beside the carboxyl methylene reagents
Can be used as the head of the special use three 】【 xiang xiang, trace for floral formula, such as lilacs, Hester prynne, jasmine, violet, acacia, sunflower, sweet bean flower, plum, orange flower, etc. Can also use the soap. Can also be used as edible spices in almond, berries, cream, a cherry, coconut, apricots, peaches, big walnut, plum, incense was, spicy flavor. Liquor flavor type such as rum and brandy in also
[use] benzaldehyde wild yan withered, plant growth regulat
