101-14-4 Usage

Chemical Properties

off-white powder

Uses

Different sources of media describe the Uses of 101-14-4 differently. You can refer to the following data:
1. MOCA is widely used in machinery, automobile, aircraft manufacturing, mining, industrial and sports facilities (such as plastic track and plastic floor) can be used for curing and waterproof coatings such as epoxy resin, which can be given to polyester and polyether elastomer most good physical and mechanical properties and the results.
2. Curing agent for polyurethanes and epoxy resins

Production Methods

The production of MOCA in the United States has ceased since 1979 and is now imported, mainly from Japan. More than 1.9 million lb was imported in 1989. The compound is currently used as a curing agent for isocyanate-containing polymers and in the manufacture of polyurethane foams, epoxy resins, gun mounts, jet engine turbine blades, radar systems, and components in home appliances. It is also a model compound for studying carcinogenesis.

Toxic. A confirmed carcinogen, absorbedby skin. Causes bladder cancer and methe-moglobinemia.

Health Hazard

4,4¢-Methylene bis(2-chloroaniline), or MOCA, is carcinogenic in experimental animals.

Fire Hazard

Flash point data for 4,4'-Methylene bis(2-chloroaniline) are not available. 4,4'-Methylene bis(2-chloroaniline) is probably combustible.

Flammability and Explosibility

Nonflammable

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by ingestion and intraperitoneal routes. Mutation data reported. Flammable liquid. Reactive with active metals such as sodium, potassium, magnesium, or zinc. When heated to decomposition it emits very toxic fumes of Cland NOx.

Carcinogenicity

4,4′-Methylenebis(2-chloroaniline) is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Check Digit Verification of cas no

The CAS Registry Mumber 101-14-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 101-14:
(5*1)+(4*0)+(3*1)+(2*1)+(1*4)=14
14 % 10 = 4
So 101-14-4 is a valid CAS Registry Number.

Interpretation of the mechanism of 3,3′-dichloro-4,4′-diamino diphenylmethane synthesis over HY zeolites

Ruan, Xiao,Wang, Qiang,Wei, Feng,Yang, Li,Zhao, Yingxian

, p. 34719 - 34728 (2020)

Catalytic activities of zeolites HY, Hβ and HZSM-5 in the heterogeneous synthesis of 3,3′-dichloro-4,4′-diaminodiphenyl methane (MOCA) fromo-chloroaniline and formaldehyde were pre-screened in an autoclave, and HY demonstrated better performance than others. Kinetic behaviors of MOCA synthesis over HY(11) were further investigated in a fixed bed continuous flow reactor, and under the conditions of the catalyst bed volume = 20 mL (8.14 g),n(o-chloroaniline) : n(HCHO) = 4 : 1, LHSV = 3.5 h?1, 0.5 MPa and 443 K, HCHO conversion and MOCA selectivity steadily fluctuated at high levels of 90-92% and 75-77% during 16 h, respectively. Catalysts were characterized by BET, NH3-TPD and XRD, products analyzed by HPLC, and reaction intermediates identified by LC/MS and1H NMR. The mechanism of MOCA synthesis has been interpreted in detail, which also suggested that deposition of basic intermediates on active sites and accumulation of polymeric by-products in pore channels of the catalyst could cause significant decay of HY(11) activity and selectivity under severe conditions. Supplementary tests on catalyst regeneration confirmed that the acidity and surface area of spent HY(11) could be well recovered after burning off the deposited by-products.
