通過(guò)這一段時(shí)間的了解,相信大家對(duì)精對(duì)苯二甲酸已經(jīng)是不陌生了,但對(duì)于想進(jìn)一步了解本產(chǎn)品的相關(guān)知識(shí)的客戶來(lái)說(shuō)這些內(nèi)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(guān)于精對(duì)苯二甲酸方面的知識(shí)與大家分享一下,希望引起大家的重視,讓大家對(duì)精對(duì)苯二甲酸有一個(gè)深層次的了解。這樣大家在購(gòu)買使用精對(duì)苯二甲酸時(shí)也能做到心中有數(shù),不慌不忙,希望對(duì)大家有所啟發(fā)與幫助。請(qǐng)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(duì)苯二甲酸親油性較大,易穿透細(xì)胞膜進(jìn)入細(xì)胞體內(nèi),干擾細(xì)胞膜的通透性,抑制細(xì)胞膜對(duì)氨基酸的吸收;進(jìn)入細(xì)胞體內(nèi)電離酸化細(xì)胞內(nèi)的堿儲(chǔ),并抑制細(xì)胞的呼吸酶系的活性,阻止乙酰輔酶A縮合反應(yīng),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(duì)苯二甲酸用于化學(xué)分析用試劑;用于醫(yī)藥工業(yè)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(fā),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(fā)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.
