USES:

1. Salicylic   acid namely ortho hydroxy benzoic acid (o-hydroxybenzoic acid) is a kind of   important organic synthetic raw material. In pesticide production, it is used   for synthetic organic phosphorus pesticide Isocarbophos, isofenphos methyl   intermediates isopropyl salicylate and Rodenticide warfarin, kill rats ether   intermediate 4-hydroxy coumarin; in the pharmaceutical industry, salicylic   acid was used as antiseptics, also as intermediates of acetylsalicylic acid   (aspirin) and other drugs; it is also an important raw material of dye,   spices, such as rubber industry .

2. It is   mainly used as raw materials of aspirin feedstock and pesticide aqueous amine   and phosphorus products, can also be used in dye industry, refining and   chemical reagent, etc.

3. Used in the   pharmaceutical industry for the antipyretic, analgesic, anti-inflammatory,   diuretic drugs, industrial dye used for direct of azo dyes and acid mordant   dyes, but also for spices, etc.

4. Used as   complexing indicator and preservative.

5. Verification   for aluminum, boron, cerium, copper, iron, lead, manganese, mercury, nickel,   silver, titanium, tungsten, vanadium, sulfite, nitrate and nitrite.   Determination of aluminum, copper, iron, thorium, titanium and uranium.   Alkali method and iodometry titration standard. The fluorescent indicator.   Complexometric indicator.

6. Salicylic   acid is an important raw material of medicine, spices, dyes, rubber   auxiliaries and other fine chemicals. In the pharmaceutical industry,   salicylic acid itself is used as antiseptics, for local cutin hyperplasia and   skin fungal infection. As for pharmaceutical intermediates, it is used for   production of ethenzamide, diuretin, acetylsalicylic acid (aspirin), sodium   salicylate and salicylamide, glibenclamide niclosamide, salicylic acid, phenyl   ester, ethyl p-hydroxybenzoate, bismuth subsalicylate, sulfasalazine and   other drugs. In the dye industry, it is used for the production of direct   yellow GR, direct grey BL, direct light brown RT, acid mordant brown G, acid   mordant yellow GG dye. Salicylic acid esters are used as spice, for example,   methyl salicylate can be used as toothpaste and other oral spices and other   spices and food spices. Used in rubber industry production antiscorching   agent, ultraviolet absorbent and foaming agent and water. Salicylic acid can   also be used as a phenolic resin curing agent, textile printing and dyeing   pulp preservatives, synthetic fiber dyeing of the expansion agent (agent) and   so on.



Storage:

Stored in   cool, dry place, under 30 in the tightly sealed, original containers. Sensitive to light. It   should be protected from moisture, away from heat/fire/direct   sun light.

Packing:

In net 25 kg   paper bags, then on pallets with shrink wrapping.

Transport:

Transport as   per general chemicals.

Shelf life:

The normal   shelf life is 24 months if it is stored under the recommended conditions. If   the storage is in a very good condition, a longer shelf life can be expected.   After 24 months, Re-inspect it each 6 months.
