1.Propri\u00e9t\u00e9 du produit<\/h3>\n

L'acide phosphorique, un compos\u00e9 inorganique, est soluble dans l'eau et les alcools. Il s'oxyde lentement dans l'air en acide orthophosphorique. \u00c0 180\u2103, il se d\u00e9compose en phosphine et en acide orthophosphorique. Il est corrosif. L'acide phosphorique est un acide binaire dans le livre de chimie. Son acidit\u00e9 est l\u00e9g\u00e8rement plus forte que celle de l'acide phosphorique. Il a une forte r\u00e9ductibilit\u00e9 et peut r\u00e9duire les ions argent (Ag+) en argent m\u00e9tallique (Ag), et peut r\u00e9duire l'acide sulfurique en dioxyde de soufre.<\/p>\n

3. Champ d'application et utilisation<\/h3>\n

Agriculture : L'acide phosphorique est la mati\u00e8re premi\u00e8re pour la production d'engrais phosphat\u00e9s importants (tels que le superphosphate, le dihydrog\u00e9nophosphate de potassium, etc.) et \u00e9galement la mati\u00e8re premi\u00e8re pour la production d'agents nutritifs pour l'alimentation animale (dihydrog\u00e9nophosphate de calcium).<\/p>\n

Industrie : L'acide phosphorique est une mati\u00e8re premi\u00e8re chimique importante. Ses principales fonctions sont les suivantes 1. Il est utilis\u00e9 pour traiter la surface des m\u00e9taux, g\u00e9n\u00e9rant des films de phosphate insolubles sur la surface du m\u00e9tal pour prot\u00e9ger le m\u00e9tal de la corrosion. 2. Il est m\u00e9lang\u00e9 \u00e0 l'acide nitrique en tant qu'agent de polissage chimique pour am\u00e9liorer la douceur de la surface du m\u00e9tal. 3. Il est utilis\u00e9 pour produire des esters de phosphate comme mati\u00e8res premi\u00e8res pour les produits de nettoyage et les pesticides. 4. Il est utilis\u00e9 pour produire des mati\u00e8res premi\u00e8res pour les retardateurs de flamme contenant du phosphore.<\/p>\n

L'alimentation : L'acide phosphorique est l'un des additifs alimentaires. Il est utilis\u00e9 comme acidulant et comme nutriment pour les levures dans les aliments. Le cola contient de l'acide phosphorique. Les sels de phosphate sont \u00e9galement des additifs alimentaires importants et peuvent \u00eatre utilis\u00e9s comme exhausteurs de nutriments.<\/p>\n

M\u00e9decine : L'acide phosphorique peut \u00eatre utilis\u00e9 pour produire des m\u00e9dicaments contenant du phosphore, tels que le glyc\u00e9rophosphate de sodium, etc.<\/p>\n

4. l'emballage et le stockage<\/h3>\n

 <\/p>\n

La zone de stockage doit \u00eatre fra\u00eeche et bien ventil\u00e9e, \u00e9loign\u00e9e des sources de feu et des temp\u00e9ratures \u00e9lev\u00e9es, et prot\u00e9g\u00e9e de la lumi\u00e8re directe du soleil.<\/p>\n

Manipulation des conteneurs : Utiliser des r\u00e9cipients r\u00e9sistants \u00e0 la corrosion (tels que le poly\u00e9thyl\u00e8ne ou le verre) et \u00e9viter tout contact avec des r\u00e9cipients m\u00e9talliques. Mesures d'isolement : Stocker s\u00e9par\u00e9ment des denr\u00e9es alimentaires, des aliments pour animaux, des oxydants et d'autres produits chimiques afin d'\u00e9viter les fuites ou les r\u00e9actions.<\/p>","protected":false},"excerpt":{"rendered":"
