通過這一段時間的了解,相信大家對精對苯二甲酸已經是不陌生了,但對于想進一步了解本產品的相關知識的客戶來說這些內容還是不夠的。
Through this period of understanding, I believe you are no stranger to PTA, but for customers who want to know more about this product, these contents are not enough.
今天小編就將關于精對苯二甲酸方面的知識與大家分享一下,希望引起大家的重視,讓大家對精對苯二甲酸有一個深層次的了解。這樣大家在購買使用精對苯二甲酸時也能做到心中有數,不慌不忙,希望對大家有所啟發與幫助。請看下面的具體闡述吧:
Today, I will share the knowledge about PTA with you, hoping to arouse your attention and let you have a deep understanding of PTA. In this way, you can have a clear idea when purchasing and using PTA. I hope it will be helpful to you. Let's see the following details:
精對苯二甲酸親油性較大,易穿透細胞膜進入細胞體內,干擾細胞膜的通透性,抑制細胞膜對氨基酸的吸收;進入細胞體內電離酸化細胞內的堿儲,并抑制細胞的呼吸酶系的活性,阻止乙酰輔酶A縮合反應,從而起到食品防腐的目的。
PTA is more lipophilic, easy to penetrate into the cell membrane, interfere with the permeability of the cell membrane, inhibit the absorption of amino acids by the cell membrane, ionize and acidify the alkali storage in the cell, inhibit the activity of respiratory enzyme system, and prevent the condensation reaction of acetyl coenzyme A, so as to achieve the purpose of food preservation.
精對苯二甲酸用于化學分析用試劑;用于醫藥工業和植物遺傳研究 苯甲酸又稱為安息香酸,故苯甲酸鈉又稱安息香酸鈉。苯甲酸在常溫下難溶于水,在空氣(特別是熱空氣)中微揮發,有吸濕性,大約常溫下0.34g/100ml;但溶于熱水;也溶于乙醇、氯仿和非揮發性油。而苯甲酸鈉在都使用苯甲酸鈉;苯甲酸和苯甲酸鈉的性狀和防腐性能都差不多。
Purified terephthalic acid is used as chemical analysis reagent; it is used in pharmaceutical industry and plant genetic research. Benzoic acid is also known as benzoic acid, so sodium benzoate is also known as sodium benzoate. Benzoic acid is difficult to dissolve in water at room temperature, slightly volatilized in air (especially in hot air), hygroscopic, about 0.34g/100ml at room temperature; but it is soluble in hot water; it is also soluble in ethanol, chloroform and non-volatile oil. Sodium benzoate is widely used in many industries; the properties and corrosion resistance of benzoic acid and sodium benzoate are similar.
