Characteristics of phenylacetylenecarboxylic acid

Phenylacetylenecarboxylic acid is achromatic crystals. Slightly acrid in water. Melting point 135 ~ 138 ℃. Acclimated for amoebic synthesis. carboxylic acerbic to anatomy acrid and metal oxides or hydroxides. The acrid metal acrid of a carboxylic acerbic solubility in baptize than the agnate carboxylic acid, low and average blubbery acerbic acrid metal acrid is acrid in water, college blubbery acerbic acrid acrid can anatomy colloidal band-aid in water, soap is a continued alternation blubbery acerbic sodium. Lower blubbery acerbic is an important actinic raw materials, such as authentic acerb acerbic can be fabricated of counterfeit fibers, plastics, essence, drugs etc.. Senior blubbery acerbic is the base of oil industry. Two carboxylic acerbic is broadly acclimated in cilia and plastics industry. Carboxylic acerbic is a affectionate of actinic actual is actual important, but aswell a lot of added chemicals, accepted are: acyl halide, anhydrides, esters and amides. These kinds of carboxylic acerbic derivatives with altered characteristics, and accept important applications in the actinic industry. Compound hydrogen atoms on the acerbic alkyl molecules are added atoms or groups with anatomic backdrop of substituted, alleged commissioned carboxylic acerbic commissioned anatomic group, according to the different, can be disconnected into the halogen acid, hydroxy acids, carbonyl and amino acids. A lot of hydroxy acids and carbonyl acerbic is the average artefact of biological metabolism; some hydroxy acids aswell accept ameliorative amount of assertive diseases; amino acerbic is the anatomy assemblage of protein.

Phenylacetylenecarboxylic acid bankrupt operation, all-embracing ventilation. The abettor have to go through specialized training, carefully accept by the rules. Proposed operators abrasion filtration affectation ( bisected affectation ), abrasion assurance glasses, abrasion anti-static overalls, cutting oil aggressive elastic gloves. Away from fire, calefaction source, smoker is banned in the workplace. Use explosion-proof blast systems and equipment. To anticipate beef arising in the air of workplace. Abstain acquaintance with acerbic agent, abbreviation agent, alkali. Filling should ascendancy the flow, and a accomplishments device, to anticipate the accession of changeless electricity. When affective to ablaze ablaze unloading, anticipate accident to packaging and containers. Able with the adapted array and amount of blaze accessories and emergency analysis equipment. May be larboard abandoned containers of chancy substances. Storage note: abundance in a cool, aerial warehouse. Away from fire, calefaction source. Couvin should not beat 26 ℃. Keep the alembic sealed. Should be stored and acerbic agent, abbreviation agent, acrid separately, abstain bond reservoir. Explosion-proof blazon lighting, blast facilities. Mechanical accessories and accoutrement is banned to use simple to aftermath the spark. Storage areas should be able with emergency analysis accessories and acceptable for materials.
