Methanesulfonic Acid

Zouping Jinxing Tshuaj Co., Ltd. Yog tias koj yuav mus rau cov lag luam wholesale bulk methanesulfonic acid ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Cov tsos mob: Cov khoom ntshiab yog xim tsis muaj xim, pob tshab oily kua; qib industrial yog daj ntseg daj. Tsis crystallize; tseem ua kua dej mus rau -20 degree.
Kub taw tes: 167℃ntawm 1.3 kPa (10 mmHg); pib decompose ntawm kwv yees li 200℃nyob rau hauv atmospheric siab (tsis txawv atmospheric boiling point).
Melting point: -19 ° C.
Qhov ceev: 1.481 g / cm³ (20 degree); denser tshaj dej.
Refractive index: n²⁰ᴅ ≈ 1.431.
Solubility: Ua tiav miscible nrog dej, ethanol, diethyl ether, DMF, thiab DMSO; insoluble nyob rau hauv hydrocarbons; aqueous kua yog muaj zog acidic.
pKa: kwv yees li -1.9 (hauv dej); acidity piv rau hydrochloric acid thiab sulfuric acid (me ntsis qaug zog dua li thawj dissociation ntawm H₂SO₄) thiab deb zog tshaj carboxylic acids los yog phenols.
Conductivity: Aqueous tov muaj siab conductivity; tuaj yeem ua cov acidic tivthaiv hauv electroplating da dej.
Tsis yog-flammable, tab sis decomposes ntawm qhov kub thiab txias kom tso pa tawm SO₂/SO₃.

Esterification / Condensation Catalysts: Biodiesel (hloov H₂SO₄; yooj yim cais, tsis muaj carbonization), polyesters, tshuaj tsw qab esterification
Electroplating / Electrolysis: Acid tivthaiv hauv plating da dej rau tin, lead, tooj liab, thiab npib tsib xee (tin methanesulfonate yields ntom coatings; kev lag luam tus qauv rau PCBs)
Pharmaceutical/Agrochemical Synthesis: MsCl intermediate, carbohydrate chemistry (glycosylation), acid pab rau peptide coupling
Roj teeb / Capacitors: Electrolyte tivthaiv rau supercapacitors (siab conductivity, dav kua kub ntau)
Tus neeg saib xyuas tu: Hlau pickling (hloov hydrochloric acid kom txo cov hydrogen embrittlement thiab chloride ion paug)

Tus neeg saib xyuas tu: Hlau pickling (hloov hydrochloric acid kom txo cov hydrogen embrittlement thiab chloride ion paug)

Toxicity: Tsawg toxicity tab sis corrosive. Qhov ncauj LD₅₀ (rat) ≈ 1.6 g / kg; dermal LD₅₀ (Lavbit) ≈ 620 mg/kg.
Corrosivity: Ua rau tawv nqaij tawv thiab qhov muag corrosion (H314); qhov muag qhov muag yuav ua rau muaj kev puas tsuaj mus tas li; inhalation ntawm huab cua ua rau ua pa ib ntsuj av tau edema.
GHS: Kev phom sij; H290 (Tej zaum yuav corrosive rau hlau), H314 (ua rau tawv nqaij kub hnyiab thiab qhov muag puas), H335 (Tej zaum yuav ua rau ua pa ua pa).
Cia thiab thauj: UN 3265 (Corrosive kua, acidic, nos, PG II); khaws cia rau hauv cov nruas yas (PE/PP) los yog yas- hlua steel nruas; tsis txhob cia nrog alkalis, oxidizing cov neeg ua haujlwm, lossis cov hmoov hlau reactive; khaws cia ntawm chav tsev kub hauv qhov dej zoo - qhov cua.
