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 purified terephthalic acid, but these contents are not enough for customers who want to further understand the relevant knowledge of this product.
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 my knowledge about PTA with you, hoping to attract your attention and let you have a deep understanding of PTA. In this way, we can know what to do when purchasing and using purified terephthalic acid. We hope to inspire and help you. Please 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。
Purified terephthalic acid is lipophilic, easy to penetrate the cell membrane into the cell body, interfere with the permeability of the cell membrane and inhibit the absorption of amino acids by the cell membrane; Enter the cell body, ionize and acidify the alkali storage in the cell, inhibit the activity of the respiratory enzyme system of the cell, 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 reagent for chemical analysis; Benzoic acid is also called benzoic acid, so sodium benzoate is also called sodium benzoate. Benzoic acid is insoluble in water at room temperature, slightly volatile in air (especially hot air) and hygroscopic, about 0.34g/100ml at room temperature; But soluble in hot water; It is also soluble in ethanol, chloroform and non-volatile oil. Sodium benzoate is used in all; The properties and anti-corrosion properties of benzoic acid and sodium benzoate are similar.
